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…
A New Look at an Old Cluster: The Membership, Rotation, and Magnetic Activity of Low-Mass Stars in the 1.3-Gyr-Old Open Cluster NGC 752
Marcel Agüeros, Emily Bowsher, John Bochanski +8
The nearby open cluster NGC 752 presents a rare opportunity to study stellar properties at ages >1 Gyr. However, constructing a membership catalog for it is challenging; most surve…
Linking Stellar Coronal Activity and Rotation at 500 Myr: A Deep Chandra Observation of M37
Alejandro Núñez, Marcel A. Agüeros, Kevin R. Covey +9
Empirical calibrations of the stellar age-rotation-activity relation (ARAR) rely on observations of the co-eval populations of stars in open clusters. We used the Chandra X-ray Obs…
SDSS J111010.01+011613.1: A New Planetary-Mass T Dwarf Member of the AB Doradus Moving Group
Jonathan Gagné, Adam J. Burgasser, Jacqueline K. Faherty +5
We present a new radial velocity measurement that, together with a trigonometric parallax, proper motion and signs of low gravity from the literature, confirms that SDSS J111010.01…
The Factory and The Beehive II. Activity and Rotation in Praesepe and the Hyades
S. T. Douglas, M. A. Agüeros, K. R. Covey +9
Open clusters are collections of stars with a single, well-determined age, and can be used to investigate the connections between angular-momentum evolution and magnetic activity o…
A Search for Photometric Variability in L and T type Brown Dwarf Atmospheres
Harish Khandrika, Adam Burgasser, Carl Melis +3
Using the Gemini infrared camera on the 3-meter Shane telescope at Lick Observatory, we have searched for broad-band J and K' photometric variability for a sample of 15 L and T-typ…
Mapping the Extended HI Distribution of Three Dwarf Galaxies
Deidre A. Hunter, Fakhri Zahedy, Emily C. Bowsher +3
We present large field HI-line emission maps obtained with the single-dish Green Bank Telescope centered on the dwarf irregular galaxies Sextans A, NGC 2366, and WLM. We do not det…
