Observations of Spin-Down in Post-Mast-Transfer Stars and the Possibility for Blue Straggler Gyrochronology
Emily Leiner, Robert Mathieu, Natalie Gosnell +1
Blue stragglers and other mass transfer/collision products are likely born with rapid rotation rates due to angular momentum transfer during mass-transfer, merger or collisional fo…
Orbital Parameters for the Two Young Binaries VSB 111 and VSB 126
Nicole Karnath, Lisa Prato, Larry Wasserman +3
We report orbital parameters for two low-mass, pre-main sequence, double-lined spectroscopic binaries VSB 111 and VSB 126. These systems were originally identified as single-lined…
The Low-mass Populations in OB Associations
Cesar Briceno, Thomas Preibisch, William Sherry +4
Low-mass stars 0.1 ~< M ~< 1 Msun) in OB associations are key to addressing some of the most fundamental problems in star formation. The low-mass stellar populations of OB associat…
The K2 M67 Study: Establishing the Limits of Stellar Rotation Period Measurements in M67 with K2 Campaign 5 Data
Rebecca Esselstein, Suzanne Aigrain, Andrew Vanderburg +4
The open cluster M67 offers the unique opportunity to measure rotation periods for solar-age stars across a range of masses, potentially filling a critical gap in the understanding…
Magnetic Field Amplification during Stellar Collisions between Low-Mass Stars
Taeho Ryu, Alison Sills, Ruediger Pakmor +2
Blue straggler stars in stellar clusters are a subset of stars that are bluer and appear younger than other cluster members, seemingly straggling behind in their evolution. They of…
Evolved Eclipsing Binaries and the Age of the Open Cluster NGC 752
Eric L. Sandquist, Andrew J. Buckner, Matthew D. Shetrone +8
We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 day binary DS An…
The K2 M67 Study: An Evolved Blue Straggler in M67 from K2 Mission Asteroseismology
Emily Leiner, Robert Mathieu, Dennis Stello +1
Yellow straggler stars (YSSs) fall above the subgiant branch in optical color-magnitude diagrams, between the blue stragglers and the red giants. YSSs may represent a population of…
HST/NICMOS Imaging Survey of the Ophiuchus (Lynds 1688) Cluster
Lori E. Allen, Philip C. Myers, James Di Francesco +3
We present a catalogue of near-infrared photometry of young stars associated with the Ophiuchus molecular cloud, based on observations made with the Hubble Space Telescope NICMOS-3…
2M17091769+3127589: a mass-transfer binary with an extreme mass ratio
Annaliese Miller, Marina Kounkel, Meng Sun +5
We present the orbital solution of a peculiar double-lined spectroscopic and eclipsing binary system, 2M17091769+3127589. This solution was obtained by a simultaneous fit of both A…
