An increased rate of large flares at intermediate rotation periods for mid-to-late M dwarfs

Nicholas Mondrik, Elisabeth Newton, David Charbonneau. Jonathan Irwin

We present an analysis of flares in mid-to-late M dwarfs in the MEarth photometric survey. We search 3985155 observations across 2226 stars, and detect 54 large () f…

TESS Discovery of an ultra-short-period planet around the nearby M dwarf LHS 3844

Roland Vanderspek, Chelsea X. Huang, Andrew Vanderburg +45

Data from the newly-commissioned \textit{Transiting Exoplanet Survey Satellite} (TESS) has revealed a "hot Earth" around LHS 3844, an M dwarf located 15 pc away. The planet has a r…

Four new eclipsing mid M-dwarf systems from the New Luyten Two Tenths catalog

Jonathan M. Irwin, David Charbonneau, Gilbert A. Esquerdo +7

Using data from the MEarth-North and MEarth-South transit surveys, we present the detection of eclipses in four mid M-dwarf systems: LP 107-25, LP 261-75, LP 796-24, and LP 991-15.…

A second terrestrial planet orbiting the nearby M dwarf LHS 1140

Kristo Ment, Jason A. Dittmann, Nicola Astudillo-Defru +27

LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and Spitzer as well as…

New rotation period measurements for M dwarfs in the southern hemisphere: an abundance of slowly rotating, fully convective stars

Elisabeth R. Newton, Nicholas Mondrik, Jonathan Irwin +2

Stellar rotation periods are valuable both for constraining models of angular momentum loss and for under- standing how magnetic features impact inferences of exoplanet parameters.…

The stellar rotation--activity relationship in fully convective M dwarfs

Nicholas J. Wright, Elisabeth R. Newton, Peter K. G. Williams +2

The coronal activity-rotation relationship is considered to be a proxy for the underlying stellar dynamo responsible for magnetic activity in solar and late-type stars. While this…
