Anchoring the Chromospheric ActivityRotation Relation: A Study of the Pleiades and Group X

A. Núñez, M. A. Agüeros, J. L. Curtis +1

We present a study of the rotation and the chromospheric H activity of low-mass stars in the 120 Myr-old Pleiades and the 400 Myr-old Group X open clusters. We…

The Factory and the Beehive. V. Chromospheric and Coronal Activity and Its Dependence on Rotation in Praesepe and the Hyades

Alejandro Núñez, M. A. Agüeros, J. L. Curtis +6

Low-mass (< 1.2 Solar mass) main-sequence stars lose angular momentum over time, leading to a decrease in their magnetic activity. The details of this rotation-activity relation re…

Using stellar rotation to identify tidally stripped members of the Praesepe open cluster

Jessica McDivitt, Stephanie T. Douglas, Jason Lee Curtis +2

As an open cluster orbits the Milky Way, gravitational fields distort it, stripping stars from the core and forming tidal tails. Recent work has identified tidal tails of the Praes…

The Factory and the Beehive. IV. A Comprehensive Study of the Rotation X-ray Activity Relation in Praesepe and the Hyades

Alejandro Núñez, Marcel A. Agüeros, Kevin R. Covey +7

X-ray observations of low-mass stars in open clusters are critical to understanding the dependence of magnetic activity on stellar properties and their evolution. Praesepe and the…

Activity and Rotation of Nearby Field M Dwarfs in the TESS Southern Continuous Viewing Zone

Francys Anthony, Alejandro Núñez, Marcel A. Agüeros +8

The evolution of magnetism in late-type dwarfs remains murky, as we can only weakly predict levels of activity for M dwarfs of a given mass and age. We report results from our spec…

Three K2 Campaigns Yield Rotation Periods for 1013 Stars in Praesepe

Rayna Rampalli, Marcel A. Agüeros, Jason L. Curtis +8

We use three campaigns of K2 observations to complete the census of rotation in low-mass members of the benchmark, 670-Myr-old open cluster Praesepe. We measure new rotati…

2MASSJ035523.51+113337.4: A Young, Dusty, Nearby, Isolated Brown Dwarf Resembling A Giant Exoplanet

Jacqueline K. Faherty, Emily L. Rice, Kelle L. Cruz +2

We present parallax and proper motion measurements, near-infrared spectra, and WISE photometry for the low surface gravity L5gamma dwarf 2MASSJ035523.37+113343.7 (2M0355). We use t…
