Evaluating Rotation Periods of M Dwarfs Across the Ages

Mark Popinchalk, Jacqueline K. Faherty, Rocio Kiman +5

In this work we examine M dwarf rotation rates at a range of ages to establish benchmarks for Mdwarf gyrochronology. This work includes a sample of 713 spectroscopically-classified…

Calibration of the Halpha Age-Activity relation for M dwarfs

Rocio Kiman, Jacqueline K. Faherty, Kelle L. Cruz +6

In this work, we calibrate the relationship between Halpha emission and M dwarf ages. We compile a sample of 892 M dwarfs with Halpha equivalent width (HaEW) measurements from the…

Weather on Other Worlds. V. The Three Most Rapidly Rotating Ultra-Cool Dwarfs

Megan E. Tannock, Stanimir Metchev, Aren Heinze +7

We present the discovery of rapid photometric variability in three ultra-cool dwarfs from long-duration monitoring with the Spitzer Space Telescope. The T7, L3.5, and L8 dwarfs hav…

Discovery of an Edge-on Circumstellar Debris Disk Around BD+45598: a Newly Identifed Member of the Pictoris Moving Group

Sasha Hinkley, Elisabeth C. Matthews, Charlène Lefevre +24

We report the discovery of a circumstellar debris disk viewed nearly edge-on and associated with the young, K1 star BD+45598 using high-contrast imaging at 2.2m obtain…

Direct imaging of sub-Jupiter mass exoplanets with James Webb Space Telescope coronagraphy

Aarynn L. Carter, Sasha Hinkley, Mariangela Bonavita +7

The James Webb Space Telescope (JWST), currently scheduled to launch in 2021, will dramatically advance our understanding of exoplanetary systems with its ability to directly image…

The Tau Association: A 60 Myr-Old Coeval Group at 150 pc from the Sun

Jonathan Gagné, Trevor J. David, Eric E. Mamajek +3

[Abbreviated] We present an analysis of the newly identified Tau Association (MUTA) of young stars at 150 pc from the Sun that is part of the large Cas-Tau structure, co…
