OrCAS: Origins, Compositions, and Atmospheres of Sub-neptunes. I. Survey Definition
Ian J. M. Crossfield, Alex S. Polanski, Paul Robertson +61
Sub-Neptunes - volatile-rich exoplanets smaller than Neptune - are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well a…
Absence of a Correlation between White Dwarf Planetary Accretion and Primordial Stellar Metallicity
Sydney Jenkins, Andrew Vanderburg, Allyson Bieryla +8
Over a quarter of white dwarfs have photospheric metal pollution, which is evidence for recent accretion of exoplanetary material. While a wide range of mechanisms have been propos…
BD-14 3065b (TOI-4987b): from giant planet to brown dwarf: evidence for deuterium burning in old age?
Ján Šubjak, David W. Latham, Samuel N. Quinn +15
The present study reports the confirmation of BD-14 3065b, a transiting planet/brown dwarf in a triple-star system, with a mass near the deuterium burning boundary. BD-14 3065b has…
The Mass Dependence of Hα Emission and Stellar Spindown for Fully Convective M Dwarfs
Emily K. Pass, David Charbonneau, David W. Latham +4
Fully convective M dwarfs typically remain rapidly rotating and magnetically active for billions of years, followed by an abrupt and mass-dependent transition to slow rotation and…
