Confirming candidate self-lensing binary detections with radial velocity measurements
Adam McMaster, Madeline-Mai Ward, Hugh J. Dickinson +6
Compact objects in approximately edge-on binary orbits with stars are able to produce a self-lensing effect, amplifying light from their companion once per orbit. To date, five whi…
A Not-So-Compact Companion: Massive, Oversize White Dwarf in a Post-Common Envelope Eclipsing Binary
Erin M. Motherway, Evan Linck, Robert D. Mathieu +5
We provide a detailed characterization of 2M07515777+1807352, a post-common envelope eclipsing binary system with a 10.3 d, nearly, but not quite, circular orbit (e = 0.02). This s…
Rotationally Driven Ultraviolet Emission of Red Giant Stars II. Metallicity, Activity, Binarity and Sub-subgiants
Don Dixon, Keivan G. Stassun, Robert D. Mathieu +2
Red Giant Branch (RGB) stars are overwhelmingly observed to rotate very slowly compared to main-sequence stars, but a few percent of them show rapid rotation and high activity, oft…
An Eclipsing Binary Comprising Two Active Red Stragglers of Identical Mass and Synchronized Rotation: A Post-Mass-Transfer System or Just Born That Way?
Keivan G. Stassun, Guillermo Torres, Marina Kounkel +7
We report the discovery of 2M0056-08 as an equal-mass eclipsing binary (EB), comprising two red straggler stars (RSSs) with an orbital period of 33.9 d. Both stars have masses of 1…
White dwarf binaries Across the H-R Diagram
Borja Anguiano, Steven R. Majewski, Keivan G. Stassun +7
We created the APOGEE-GALEX-\emph{Gaia} catalog to study white dwarfs binaries. This database aims to create a minimally biased sample of WD binary systems identified from a combin…
Stellar multiplicity and stellar rotation: Insights from APOGEE
Christine Mazzola Daher, Carles Badenes, Jamie Tayar +18
We measure rotational broadening in spectra taken by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey to characterise the relationship between stellar mul…
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…
A KELT-TESS Eclipsing Binary in a Young Triple System Associated with a "Stellar String" Theia 301
Joni-Marie Clark Cunningham, Dax L. Felix, Don M. Dixon +7
HD 54236 is a nearby, wide common-proper-motion visual pair that has been previously identified as likely being very young by virtue of strong X-ray emission and lithium absorption…
Rotationally Driven Ultraviolet Emission of Red Giant Stars
Don Dixon, Jamie Tayar, Keivan G. Stassun
Main sequence stars exhibit a clear rotation-activity relationship, in which rapidly rotating stars drive strong chromospheric/coronal ultraviolet and X-ray emission. While the vas…
Infrared Photometric Properties of 709 Candidate Stellar Bowshock Nebulae
Henry A. Kobulnicky, Danielle P. Schurhammer, Daniel J. Baldwin +4
Arcuate infrared nebulae are ubiquitous throughout the Galactic Plane and are candidates for partial shells, bubbles, or bowshocks produced by massive runaway stars. We tabulate in…
A comprehensive search for stellar bowshock nebulae in the Milky Way: a catalog of 709 mid-infrared selected candidates
Henry A. Kobulnicky, William T. Chick, Danielle P. Schurhammer +8
We identify 709 arc-shaped mid-infrared nebula in 24 micron Spitzer Space Telescope or 22 micron Wide Field Infrared Explorer surveys of the Galactic Plane as probable dusty inters…
