HST/WFC3 Light Curve Supports a Terrestrial Composition for the Closest Exoplanet to Transit an M Dwarf
Emily K Pass, Jennifer G Winters, David Charbonneau +6
Previous studies of the exoplanet LTT 1445Ac concluded that the light curve from the Transiting Exoplanet Survey Satellite (TESS) was consistent with both grazing and non-grazing g…
LHS 475 b: A Venus-sized Planet Orbiting a Nearby M Dwarf
Kristo Ment, David Charbonneau, Jonathan Irwin +10
Based on photometric observations by TESS, we present the discovery of a Venus-sized planet transiting LHS 475, an M3 dwarf located 12.5 pc from the Sun. The mass of the star is $0…
Constraints on the Spindown of Fully-Convective M Dwarfs Using Wide Field Binaries
Emily K. Pass, David Charbonneau, Jonathan M. Irwin +1
M dwarfs remain active over longer timescales than their Sunlike counterparts, with potentially devastating implications for the atmospheres of their planets. However, the age at w…
Final Report for SAG 22: A Target Star Archive for Exoplanet Science
Natalie R. Hinkel, Joshua Pepper, Christopher C. Stark +33
Present and upcoming NASA missions will be intensively observing a selected, partially overlapping set of stars for exoplanet studies. Key physical and chemical information about t…
Distance Dependent Offsets between Parallaxes for Nearby Stars and Gaia DR1 Parallaxes
Wei-Chun Jao, Todd J. Henry, Adric R. Riedel +3
We use 612 single stars with previously published trigonometric parallaxes placing them within 25 pc to evaluate parallaxes released in Gaia's first data release (DR1). We find tha…
Speckle Imaging Excludes Low-Mass Companions Orbiting the Exoplanet Host Star TRAPPIST-1
Steve B. Howell, Mark E. Everett, Elliott P. Horch +4
We have obtained the highest resolution images available of TRAPPIST-1 using the Gemini-South telescope and our speckle imaging camera. Observing at 692 and 883 nm, we reached the…
