Shadows of Other Worlds Two Telescopes Due to Launch This Year Should Reveal a Host of New Exoplanets by Joshua N
ORBITING A RED DWARF, this imagined planet has its own moon. Both are bathed in a warm glow from the star and its flares.

Winn Illustrations by Ron Miller sad0318Winn4p.indd 32 1/23/18 4:54 PM IN BRIEF The world’s most prolific planet-hunting satellite, NASA’s Kepler spacecraft, is preparing to shut down, but several new missions target- ing exoplanets are due to launch this year. The Transiting Exoplanet Survey Satellite (TESS) and the Characterising Exoplanet Satellite ( CHEOPS) will both search for signs of other worlds crossing in front of their parent stars. Scientists stand to add many SHADOWS OF OTHER WORLDS more exoplanets to the grow- ing tally, which should help them get closer to answering two questions: Are there oth- er habitable worlds out there, and is there life beyond Earth in the universe?

Exoplanetary Atmospheres: Key Insights, Challenges and Prospects
Exoplanetary Atmospheres: Key Insights, Challenges and Prospects Nikku Madhusudhan1 1Institute of Astronomy, University of Cambridge, Cambridge, UK, CB3 0HA; email: [email protected] xxxxxx 0000. 00:1{59 Keywords Copyright c 0000 by Annual Reviews. Extrasolar planets, exoplanetary atmospheres, planet formation, All rights reserved habitability, atmospheric composition Abstract Exoplanetary science is on the verge of an unprecedented revolution. The thousands of exoplanets discovered over the past decade have most recently been supplemented by discoveries of potentially habitable planets around nearby low-mass stars. Currently, the ﬁeld is rapidly progressing towards detailed spectroscopic observations to characterise the atmospheres of these planets. While various surveys from space and ground are expected to detect numerous more exoplanets orbiting nearby stars, the imminent launch of JWST along with large ground- based facilities are expected to revolutionise exoplanetary spectroscopy. Such observations, combined with detailed theoretical models and in- verse methods, provide valuable insights into a wide range of physi- cal processes and chemical compositions in exoplanetary atmospheres. Depending on the planetary properties, the knowledge of atmospheric compositions can also place important constraints on planetary forma- tion and migration mechanisms, geophysical processes and, ultimately, arXiv:1904.03190v1 [astro-ph.EP] 5 Apr 2019 biosignatures. In the present review, we will discuss the modern and future landscape of this frontier area of exoplanetary atmospheres. We will start with a brief review of the area, emphasising the key insights gained from diﬀerent observational methods and theoretical studies. This is followed by an in-depth discussion of the state-of-the-art, chal- lenges, and future prospects in three forefront branches of the area.

Instrumentation for the Detection and Characterization of Exoplanets
Instrumentation for the detection and characterization of exoplanets Francesco Pepe1, David Ehrenreich1, Michael R. Meyer2 1Observatoire Astronomique de l'Université de Genève, 51 ch. des Maillettes, 1290 Versoix, Switzerland 2Swiss Federal Institute of Technology, Institute for Astronomy, Wolfgang-Pauli-Strasse 27, 8093 Zurich, Switzerland In no other field of astrophysics has the impact of new instrumentation been as substantial as in the domain of exoplanets. Before 1995 our knowledge about exoplanets was mainly based on philosophical and theoretical considerations. The following years have been marked, instead, by surprising discoveries made possible by high-precision instruments. More recently the availability of new techniques moved the focus from detection to the characterization of exoplanets. Next- generation facilities will produce even more complementary data that will lead to a comprehensive view of exoplanet characteristics and, by comparison with theoretical models, to a better understanding of planet formation. Astrometry is the most ancient technique of astronomy. It is therefore not surprising that the first (unconfirmed) detection of an extra-solar planet arose through this technique1. In 1984, another detection of a planetary-mass object around the nearby star VB 8 was claimed, this time using speckle interferometry2, but subsequent attempts to locate it were unsuccessful. It was finally Doppler velocimetry that delivered the first unambiguous detection of a probable brown dwarf around HD 1147623. In 1992, a handful of bodies of terrestrial mass were found4 and confirmed, by the measurement of timing variation, to orbit the pulsar PSR1257+12. Although very powerful, this technique was restricted to a small number of very particular hosts.

Exoplanet Science Review 2015

For most of human history attempts to answer this question have been lim- ited to studies of environments within our own Solar System. Today we are on the brink of being able to answer the question directly by determining the detailed properties of exoplanets – planets orbiting stars other than the Sun. Following the discovery of the first exoplanets, found just twenty years ago, there are now more than one thousand confirmed planets, and thousands of candidates, exoplanets ranging from giant planets larger than Jupi- ter to smaller Earth-sized objects. We now know that the Solar System is far from being the archetype for all plan- etary systems; indeed the complexity and diversity of exoplanetary systems and how they change over time has been a revelation. The UK has been strongly involved in exoplanet research since the early days, leveraging its expertise in astronomy and solar system science, contributing to studies ranging from the discovery of planets and determination of their sizes and masses, to detection of molecules in exoplanetary atmospheres, through to the development of theoretical models of planetary atmospheres/interiors and the formation and evolution of plane- tary systems.

The Transiting Exoplanet Survey Satellite Promises to Discover Small Planets Around the Nearest and Brightest Stars
A Quick Look into the first year of discoveries from TESS Full Frame Images: Chelsea Huang (MIT) The Transiting Exoplanet Survey Satellite promises to discover small planets around the nearest and brightest stars. After the first year of observations, the TESS mission has recovered more than a thousand planetary candidates in the Full Frame Images around bright stars. In this talk, we present a quick look into the TESS Full Frame Image data and some of its exciting discoveries from it. Using these discoveries as examples, I will review the process of planetary candidate identification in TESS Full Frame Images using the MIT Quick Look Pipeline and discuss the potential of space-based wide-field transit survey. Wide-field high-precision photometry with NGTS: Peter Wheatley (University of Warwick) Ultra-High Precision Photometry with NGTS Multi-Telescopes :Ed Bryant (University of Warwick) The Next Generation Transit Survey (NGTS) is an exoplanet hunting facility consisting of 12x20cm aperture robotic telescopes, situated at ESO's Paranal Observatory. I will present a new mode of observing in which we observe bright stars simultaneously with multiple NGTS telescopes/cameras. Using this observing method, we can obtain ultra-high precision light curves with precisions comparable to TESS. NGTS is able to monitor very bright stars (V < 9.5 mag), because the very wide field-of-view (8deg2) of NGTS provides us with the necessary number of comparison stars. Obtaining these bright star light curves is crucial for refining transit ephemerides and planetary radii for future atmospheric characterisation studies. With these ultra-high precision light curves, we can also achieve transit timing precisions on the order of 10s.
