A spectroscopically confirmed Gaia-selected sample of 318 new young stars within 200 pc
Maruša Žerjal, Adam D. Rains, Michael J. Ireland +7
In the Gaia era, the majority of stars in the Solar neighbourhood have parallaxes and proper motions precisely determined while spectroscopic age indicators are still missing for a…
A KELT-TESS Eclipsing Binary in a Young Triple System Associated with a "Stellar String" Theia 301
Joni-Marie Clark Cunningham, Dax L. Felix, Don M. Dixon +7
HD 54236 is a nearby, wide common-proper-motion visual pair that has been previously identified as likely being very young by virtue of strong X-ray emission and lithium absorption…
TOI-811b and TOI-852b: New transiting brown dwarfs with similar masses and very different radii and ages from the TESS mission
Theron W. Carmichael, Samuel N. Quinn, George Zhou +17
We report the discovery of two transiting brown dwarfs (BDs), TOI-811b and TOI-852b, from NASA's Transiting Exoplanet Survey Satellite mission. These two transiting BDs have simila…
TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars
Ismael Mireles, Avi Shporer, Nolan Grieves +40
We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exo…
