Understanding Exoplanet Atmospheres with UV Observations II: The Far UV and Atmospheric Escape [PDF]
arXiv, 2019 Much of the focus of exoplanet atmosphere analysis in the coming decade will be at infrared wavelengths, with the planned launches of the James Webb Space Telescope (JWST) and the Wide-Field Infrared Survey Telescope (WFIRST). However, without being placed in the context of broader wavelength coverage, especially in the optical and ultraviolet ...

Impact of Exoplanet Science on Society: Professional Contributions, Citizen Science Engagement and Public Perception [PDF]
arXivThe impact of exoplanet science on both the scientific community and on the general public is presented through various indicators and examples. It is estimated that about 3-4% of all refereed astronomy articles focus on exoplanets, and between 15-20% percent of current, and up to 25% of upcoming astronomy space missions are dedicated to exoplanet ...

Infrared-Radio-follow-up Observations for Detection of the Magnetic Radio Emission of Extra-Solar Planets: A New Window to Detect Exoplanets [PDF]
There are several methods for indirectly detecting exoplanets, such as transit, radial velocity, astrometry, and the conventional gravitational microlensing approach. These methods rely on observing the effects of exoplanets on the emission or motion of observed stars. All these techniques have focused on the optical or infrared domains.

Helium in the Extended Atmosphere of the Warm Superpuff TOI-1420b
The Astronomical JournalSuperpuffs are planets with exceptionally low densities ( ρ ≲ 0.1 g cm ^−3 ) and core masses ( M _c ≲ 5 M _⊕ ). Many lower-mass ( M _p ≲ 10 M _⊕ ) superpuffs are expected to be unstable to catastrophic mass loss via photoevaporation and/or boil-off ...

Early Accretion of Large Amounts of Solids for Directly Imaged Exoplanets
The Astrophysical JournalAs the number of planetary-mass objects (PMOs; ⪅13 M _Jupiter ) at wider separation (⪆10 au) grows, there is emerging evidence that they form differently from their higher-mass brown dwarf counterparts.

Ground-Based Direct Detection of Exoplanets with the Gemini Planet Imager (GPI) [PDF]
arXiv, 2007 The Gemini Planet (GPI) imager is an "extreme" adaptive optics system being designed and built for the Gemini Observatory. GPI combines precise and accurate wavefront control, diffraction suppression, and a speckle-suppressing science camera with integral field and polarimetry capabilities.

Biases from Missing a Small Planet in High Multiplicity Systems
The Astrophysical Journal LettersIn an era when we are charting multiple planets per system, one might wonder the extent to which “missing” (or failing to detect) a planet can skew our interpretation of the system architecture. We address this question with a simple experiment: starting

Exoplanet Detection : A Detailed Analysis [PDF]
arXivThe exoplanet detection is the most exciting and challenging field of astronomy. The discovery of many exoplanets has revolutionized our understanding of the formation and evolution of planetary systems and has showed new ways to search for extra terrestrial life.
