  • Introduction (PDF)
    Section Name –YUDHIJIT BHATTACHARJEE AND DANIEL CLERY In 1992, astronomers announced that a whirling neutron star our sun, but others are truly alien: hot Jupiters, mini-Neptunes, called a millisecond pulsar harbored the fi rst known planets outside super-Earths. our solar system: extrasolar planets, or exoplanets. Two decades on, To help readers navigate the bewildering variety of new worlds exoplanets are practically an astronomical commodity. Nearly 900 and their discoverers, Science presents this guide for the perplexed: of them have been confi rmed, and hundreds of fresh candidates are an overview of planet-hunting techniques and representative efforts, turning up every month. Some resemble the familiar orbs circling followed by an informal glossary of popular exo-objects. Radial velocity measurement is the mother of exoplanet search techniques. Michel Mayor and Didier Queloz of the Observa- tory of Geneva in Switzerland used it in 1995 to make the fi rst confi rmed detection of an exoplanet around a sunlike star, and it’s still going strong. As a planet orbits a star, its gravity causes the star to move around their com- mon center of gravity, usually inside the star. If we view such a system edge-on, the star would appear to be wobbling from side to side. Current telescopes can’t on May 4, 2013 detect such tiny movements, but they can spot a wobble back and forth along the line of sight because such changes in radial velocity raise and lower the frequency of the star’s light. To spot exoplanets this way, astronomers don’t need a huge telescope or one in S space—just an extremely sensitive spectrometer and lots of time.

K2-138 is an orangish (K1) main sequence star about 200 parsecs away, with five known planets all between the size of Earth and Neptune orbiting in a very compact architecture. The planet’s orbits form an unbroken chain of 3:2 resonances, with orbital periods ranging from 2.3 and 12.8 days, orbiting the star between 0.03 and 0.10 AU. The limb of the hot sub-Neptunian world K2-138 f looms in the foreground at the bottom, with close neighbor K2-138 e visible (center) and the innermost planet K2-138 b transiting its star.

  • Astro2010: the Astronomy and Astrophysics Decadal Survey
    Astro2010: The Astronomy and Astrophysics Decadal Survey Notices of Interest 1. 4 m space telescope for terrestrial planet imaging and wide field astrophysics Point of Contact: Roger Angel, University of Arizona Summary Description: The proposed 4 m telescope combines capabilities for imaging terrestrial exoplanets and for general astrophysics without compromising either. Extremely high contrast imaging at very close inner working angle, as needed for terrestrial planet imaging, is accomplished by the powerful phase induced amplitude apodization method (PIAA) developed by Olivier Guyon. This method promises 10-10 contrast at 2.0 l/D angular separation, i.e. 50 mas for a 4 m telescope at 500 nm wavelength. The telescope primary mirror is unobscured with off-axis figure, as needed to achieve such high contrast. Despite the off-axis primary, the telescope nevertheless provides also a very wide field for general astrophysics. A 3 mirror anastigmat design by Jim Burge delivers a 6 by 24 arcminute field whose mean wavefront error of 12 nm rms, i.e.diffraction limited at 360 nm wavelength. Over the best 10 square arcminutes the rms error is 7 nm, for diffraction limited imaging at 200 nm wavelength. Any of the instruments can be fed by part or all of the field, by means of a flat steering mirror at the exit pupil. To allow for this, the field is curved with a radius equal to the distance from the exit pupil. The entire optical system fits in a 4 m diameter cylinder, 8 m long. Many have considered that only by using two spacecraft, a conventional on-axis telescope and a remote occulter, could high contrast and wide field imaging goals be reconciled.

  • 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.
