Planetary population of solar-like stars and overview of statistical results? Alexandre Emsenhuber1; 2, Christoph Mordasini2, Remo Burn2, Yann Alibert2, Willy Benz2, and Erik Asphaug1 1 Lunar and Planetary Laboratory, University of Arizona, 1629 E. University Blvd., Tucson, AZ 85721, USA e-mail: [email protected] 2 Physikalisches Institut, Universität Bern, Gesselschaftsstrasse 6, 3012 Bern, Switzerland Received DD MMM YYYY / Accepted DD MMM YYYY ABSTRACT Context. Planetary formation and evolution is a combination of multiple processes that are interlinked. These processes are not known in detail and many uncertainties remain. Constraining the formation and evolution mechanisms observationally requires statistical comparison to a large diversity of planetary systems. Aims. We want to understand the global observable consequences of different physical processes (accretion, migration, and interac- tions) and initial properties (such as disc masses and metallicities) on the demographics of the planetary population. We also want to study the convergence of our scheme with respect to one initial condition, the initial number of planetary embryo in each disc. Methods. We select distributions of initial conditions that are representative of known protoplanetary discs. Then, we use the Gener- ation III Bern model to perform planetary population synthesis. We synthesise five populations with each a different initial number of Moon-mass embryos per disc: 1, 10, 20, 50, and 100. The last is our nominal planetary population consisting of 1000 stars (systems) that we use to provide an extensive statistical analysis of the planetary systems around 1 M stars. -

INDIA AIMS TO BE 1ST COUNTRY TO LAND ROVER ON MOON'S SOUTH POLE India will become the first country to land a rover on the Moon's the south pole if the country's space agency "Indian Space Research Organisation (ISRO)" successfully achieves the feat during the country's second Moon mission "Chandrayaan-2" later this year. "This is a place where nobody has gone. All the ISRO missions till now to the Moon have landed near the Moon's equator. Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). The Orbiter and Lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle. The Rover is housed inside the Lander. After launch into earth bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, Lander will separate from the Orbiter and soft land at the predetermined site close to lunar South Pole. -

Jocelyn Bell Burnell
Jocelyn Bell Burnell President of the Royal Astronomical Society 2002 to 2004 President of the Institute of Physics 2008 to 2010 Elected Pro-Chancellor of the University of Dublin 2013 Elected President of the Royal Society of Edinburgh 2014 B.S University of Glasgow (1965) Ph.D., Radio Astronomy, University of Cambridge (1968) Biography Jocelyn Bell Burnell was born in 1943 in Northern Ireland to Allison and Phillip Bell. She discovered her passion for astronomy early in life through books. At Lurgan College, she began her higher education but was restricted from studying science due to her gender. At the time, women were not allowed to study science at the school. Her parents were committed to the education of their daughter so when Jocelyn was unable to pass the entrance examine for continuing education her parents sent her to a Quaker boarding school. At the age of 22, she graduated from the University of Glasgow with a degree in Physics and then went on to earn her doctorate at the University of Cambridge. Presently she is working as a visiting Professor or Astrophysics at the University of Oxford. Research Jocelyn Bell Brunell’s groundbreaking research began during her time at Cambridge. She was involved in the development of a radio telescope to track quasars and after its completion became the telescope operator in charge of analyzing data collected. It was during this time that she discovered an anomaly in the data, which led her to the discovery of pulsars. This discovery lead to the 1974 Nobel Prize in Physics awarded to the lead researcher Antony Hewish along with Marti Ryle. -
Exoplanet Demographics Conference November 9-13, 2020 Tuesday Talk Abstracts
Exoplanet Demographics Conference November 9-13, 2020 Tuesday Talk Abstracts Small Planets Low-mass Exoplanet Demographics - Daniel Jontof-Hutter (Univ. of the Pacific) Exoplanet science is advancing rapidly on many fronts following the detection of thousands of planets, particularly from transit surveys. Precise stellar characterization has revealed the bimodal planetary size distribution, and has enabled precise planetary mass measurements with radial velocities and transit timing. Over 120 exoplanets less massive than 30 Earths have measured masses and radii (Jontof-Hutter, 2019, AREPS, 47, 141), and a remarkably diverse range of bulk densities among these exoplanets has been revealed. Planetary mass and radius characterization has also entered the terrestrial regime- over 30 exoplanets smaller than 1.6 Earth-radii have detected masses, and planets as small as Mars now populate the mass-radius diagram. In this review, we summarize the progress that has been made in characterizing this diverse population: where planet sizes and incident fluxes inform on bulk planet properties, where compositions by volume are dominated by volatiles and where bulk planet properties within individuals systems differ substantially. To some extent, however, detection biases prevent individual characterizations from revealing underlying planet demographics. We review progress to correct for these biases in determining distributions of planet properties. Looking forward, planetary system demographics will require observations to probe system architectures beyond the compact configurations that have been detected close to stellar hosts. A small number of compact multi-transiting systems show evidence of additional planets from radial velocities, and observing campaigns to detect non-transiting planets that orbit beyond the known planets have begun.
