The Tierras Observatory: An ultra-precise photometer to characterize nearby terrestrial exoplanets
Juliana García-Mejía, David Charbonneau, Daniel Fabricant +4
We report on the status of the Tierras Observatory, a refurbished 1.3-m ultra-precise fully-automated photometer located at the F. L. Whipple Observatory atop Mt. Hopkins, Arizona.…
Two young planetary systems around field stars with ages between 20-320 Myr from TESS
George Zhou, Samuel N. Quinn, Jonathan Irwin +46
Planets around young stars trace the early evolution of planetary systems. We report the discovery and validation of two planetary systems with ages Myr from observa…
The Volume-Complete Sample of M Dwarfs with Masses 0.1 <= M/M_sol <= 0.3 within 15 Parsecs
Jennifer G. Winters, David Charbonneau, Todd J. Henry +4
M dwarfs with masses 0.1 <= M/M_sol <= 0.3 are under increasing scrutiny because these fully convective stars pose interesting astrophysical questions regarding their magnetic acti…
The Magellan-TESS Survey I: Survey Description and Mid-Survey Results
Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66
revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…
Flare Rates, Rotation Periods. and Spectroscopic Activity Indicators of a Volume-Complete Sample of Mid-to-Late M dwarfs within 15 Parsecs
Amber A. Medina, Jennifer G. Winters, Jonathan M. Irwin +1
We present a study of flare rates, rotation periods, and spectroscopic activity indicators of 125 single stars within 15 parsecs and with masses between 0.10.3 observe…
TOI 540 b: A Planet Smaller than Earth Orbiting a Nearby Rapidly Rotating Low-mass Star
Kristo Ment, Jonathan Irwin, David Charbonneau +20
We present the discovery of TOI 540 b, a hot planet slightly smaller than Earth orbiting the low-mass star 2MASS J05051443-4756154. The planet has an orbital period of $P = 1.23914…
