Lurking in the Shadows: Wide-Separation Gas Giants As Tracers of Planet Formation
Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born. -
Mutation Breeding in Pepper S

DASKALOV* Plant Breeding Unit, Joint FAO/IAEA Division of Isotope and Radiation Applications of Atomic Energy for Food and Agricultural Development, Seibersdorf Laboratory, IAEA, Vienna Abstract Pepper (Capsicum sp, ) is an important vegetable and spice crop widely grown in tropical as well as in temperate regions. Until recently the improvement programmes were based mainly on using natural sources of germ plasm, crossbreeding and exploiting the heterosis of F hybrids. However, interest in using induced mutations is growing. A great number of agronomically useful mutants as well as mutants valuable for genetic, cytological and physiological studies have been induced and described. Acknowledgements: The author expresses his gratitude to Dr. A. Micke, Head, Plant Breeding and Genetics Section, FAO/IAEA Joint Division and to Dr. T. Hermelin, Head, Agriculture Laboratory, Joint FAO/IAEA Programme, Seibersdorf Laboratory, for their critical review of the manuscript and valuable contributions. * Permanent Address: Institute of Genetics, Sofia 1113, Bulgaria 32/ 22 In this review information is presented about suitable mutagen treatment procedures with radiation as well as chemicals, M effects, handling the treated material in M , M and subsequent generations, and mutant screening procedures. This is supplemented by a description of reported useful mutants and released cultivars. Finally, general advice is given on when and how to incorporate mutation induction in Capsicum improvement programmes.

Catalog of Nearby Exoplanets
Catalog of Nearby Exoplanets1 R. P. Butler2, J. T. Wright3, G. W. Marcy3,4, D. A Fischer3,4, S. S. Vogt5, C. G. Tinney6, H. R. A. Jones7, B. D. Carter8, J. A. Johnson3, C. McCarthy2,4, A. J. Penny9,10 ABSTRACT We present a catalog of nearby exoplanets. It contains the 172 known low- mass companions with orbits established through radial velocity and transit mea- surements around stars within 200 pc. We include 5 previously unpublished exo- planets orbiting the stars HD 11964, HD 66428, HD 99109, HD 107148, and HD 164922. We update orbits for 90 additional exoplanets including many whose orbits have not been revised since their announcement, and include radial ve- locity time series from the Lick, Keck, and Anglo-Australian Observatory planet searches. Both these new and previously published velocities are more precise here due to improvements in our data reduction pipeline, which we applied to archival spectra. We present a brief summary of the global properties of the known exoplanets, including their distributions of orbital semimajor axis, mini- mum mass, and orbital eccentricity. Subject headings: catalogs — stars: exoplanets — techniques: radial velocities 1Based on observations obtained at the W. M. Keck Observatory, which is operated jointly by the Uni- versity of California and the California Institute of Technology. The Keck Observatory was made possible by the generous financial support of the W. M. Keck Foundation. arXiv:astro-ph/0607493v1 21 Jul 2006 2Department of Terrestrial Magnetism, Carnegie Institute of Washington, 5241 Broad Branch Road NW, Washington, DC 20015-1305 3Department of Astronomy, 601 Campbell Hall, University of California, Berkeley, CA 94720-3411 4Department of Physics and Astronomy, San Francisco State University, San Francisco, CA 94132 5UCO/Lick Observatory, University of California, Santa Cruz, CA 95064 6Anglo-Australian Observatory, PO Box 296, Epping. -

Katherina Feng1,4, Jason T. Wright1, Benjamin Nelson1, Sharon X. Wang1, Eric B. Ford1, Geoffrey W. Marcy2, Howard Isaacson2, and Andrew W. Howard3 (Received 2014 August 11; Accepted 2014 November 26) Draft version September 24, 2018 ABSTRACT We present an update to seven stars with long-period planets or planetary candidates using new and archival radial velocities from Keck-HIRES and literature velocities from other telescopes. Our updated analysis better constrains orbital parameters for these planets, four of which are known multi- planet systems. HD 24040 b and HD 183263 c are super-Jupiters with circular orbits and periods longer than 8 yr. We present a previously unseen linear trend in the residuals of HD 66428 indicative on an additional planetary companion. We confirm that GJ 849 is a multi-planet system and find a good orbital solution for the c component: it is a 1MJup planet in a 15 yr orbit (the longest known for a planet orbiting an M dwarf). We update the HD 74156 double-planet system. We also announce the detection of HD 145934 b, a 2MJup planet in a 7.5 yr orbit around a giant star. Two of our stars, HD 187123 and HD 217107, at present host the only known examples of systems comprising a hot Jupiter and a planet with a well constrained period > 5 yr, and with no evidence of giant planets in between. -

Dean of College of Science & Engineering A SEARCH FOR VARIABILITY AND TRANSIT SIGNATURES IN HIPPARCOS PHOTOMETRIC DATA Badrinath Thirumalachari San Francisco State University 2018 The study and characterization of exoplanets has picked up pace rapidly over the past few decades with the invention of newer techniques and instruments. Detecting transits in stellar photometric data around stars already known to harbor exoplanets is crucial for exoplanet characterization. Due to these advancements we now have oceans of data and coming up with an automated way of performing exoplanet characterization is a challenge. In this thesis I describe one such method to search for transits in Hipparcos dataset containing photometric data for over 118000 stars. The radial velocity method has discovered a lot of planets around bright host stars and a follow up transit detection will give us the density of the exoplanet. -
Genetic Modification for Agriculture—Proposed Revision of GMO Regulation in Australia
plants Opinion Genetic Modification for Agriculture—Proposed Revision of GMO Regulation in Australia Robert Redden RJR Agriculture Consultants, 62 Schier Drive, Horsham 340, Australia; [email protected] Abstract: Genetic engineering (GM) of crops, modified with DNA transfer between species, has been highly regulated for over two decades. Now, genome editing (GE) enables a range of DNA alterations, from single base pair changes to precise gene insertion with site-directed nucleases (SDNs). Past regulations, established according to the precautionary principle of avoiding potential risks to human health and the environment, are predicated on fears fanned by well-funded and emotional anti-GM campaigns. These fears ignore the safety record of GM crops over the last 25 years and the benefits of GM to crop productivity, disease and pest resistance, and the environment. GE is now superseding GM, and public education is needed about its benefits and its potential to meet the challenges of climate change for crops. World population will exceed 9 billion by 2050, and world CO2 levels are now over 400 ppm in contrast with a pre-industrial 280 ppm, leading to a projected 1.5 ◦C global warming by 2050, with more stressful crop environments. The required abiotic and biotic stress tolerances can be introgressed from crop wild relatives (CWR) into domestic crops via GE. Restrictive regulations need to be lifted to facilitate GE technologies for sustainable agriculture in Australia and the world.

Plant Genetics – History of Genetic Modification of Crops We Eat
Plant Genetics – History of Genetic Modification of Crops We Eat WHAT? • Virtually all plants we eat have been genetically changed or modified by humans • This means we have been determining what genes or traits are propagated WHY? • Modifying and selecting plants that have desired traits for yield, taste, quality, texture, disease resistance, etc. benefit farmers and consumers • Responsible for half of crop yield improvements over the last 50 years HOW? • Natural mutations in genes or DNA • 10,000 years ago humans begin to select and breed crops • Crossbreeding of plants of the same species • Mid 1800’s modern genetics began with Gregor Mendel cross pollination of peas • To improve existing plant characteristics by crossing two varieties ….. • 1940s- Man-made mutations or mutation breeding using chemicals and radiation to create new plant varieties • Example: Ruby red grapefruit which is cold tolerant Source: Biofortified.org • 1980s- GMOs or genetically modified organisms: Scientists learned to copy a gene (DNA code) from one organism to another to add a new desired trait called transgenes using gene engineering (GM/GE). • 1990s first GMOs on the market • 2015- Gene editing makes a tiny, controlled, modification of a gene by editing the DNA code • Works like find and replace in word processor for specific, known genes which are modified without changing other genes Source: University of California, Berkley GM/GMO Crops: What’s in a name? • Genetically Modified Organism or GMO is commonly used to describe several terms: • Genetically modified (GM) • Genetic engineering (GE) • Biotech seeds • GMO refers a modern method of breeding that improves plant genetics by adding a gene(s) to a plant by “directly inserting” the gene or DNA from another organism into the genetic code to add a new trait such as insect or disease resistance, drought tolerance or enhance nutrition. -

The assessment of the frequency of planetary systems reproducing the solar system’s architecture is still an open problem in exoplanetary science. Detailed study of multiplicity and architecture is generally hampered by limitations in quality, temporal extension and observing strategy, causing difficulties in detecting low-mass inner planets in the presence of outer giant planets. Aims. We present the results of high-cadence and high-precision HARPS observations on 20 solar-type stars known to host a single long-period giant planet in order to search for additional inner companions and estimate the occurence rate fp of scaled solar system analogues – in other words, systems featuring lower-mass inner planets in the presence of long-period giant planets.
