The young planetary system K2-25: constraints on companions and starspots
Isabel J. Kain, Elisabeth R. Newton, Jason A. Dittmann +5
The abundance of planets with orbital periods of a few to tens of days suggests that exoplanets experience complex dynamical histories. Planets in young stellar clusters or associa…
Magnetic Inflation and Stellar Mass. V. Intensification and saturation of M dwarf absorption lines with Rossby number
Philip S. Muirhead, Mark J. Veyette, Elisabeth R. Newton +2
In young sun-like stars and field M dwarf stars, chromospheric and coronal magnetic activity indicators such as H, X-ray and radio emission are known to saturate with low Rossby…
A well aligned orbit for the 45 Myr old transiting Neptune DS Tuc Ab
G. Zhou, J. N. Winn, E. R. Newton +18
DS Tuc Ab is a Neptune-sized planet that orbits around a member of the 45 Myr old Tucana-Horologium moving group. Here, we report the measurement of the sky-projected angle between…
Zodiacal Exoplanets in Time (ZEIT) IX: a flat transmission spectrum and a highly eccentric orbit for the young Neptune K2-25b as revealed by Spitzer
Pa Chia Thao, Andrew W. Mann, Marshall C. Johnson +9
Transiting planets in nearby young clusters offer the opportunity to study the atmospheres and dynamics of planets during their formative years. To this end, we focused on K2-25b -…
TESS Hunt for Young and Maturing Exoplanets (THYME): A planet in the 45 Myr Tucana-Horologium association
Elisabeth R. Newton, Andrew W. Mann, Benjamin M. Tofflemire +49
Young exoplanets are snapshots of the planetary evolution process. Planets that orbit stars in young associations are particularly important because the age of the planetary system…
A super-Earth and sub-Neptune transiting the late-type M dwarf LP 791-18
Ian J. M. Crossfield, William Waalkes, Elisabeth R. Newton +57
Planets occur most frequently around cool dwarfs, but only a handful of specific examples are known to orbit the latest-type M stars. Using TESS photometry, we report the discovery…
