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…
Multiplicity Statistics of Stars in the Sagittarius Dwarf Spheroidal Galaxy: Comparison to the Milky Way
Victoria Bonidie, Travis Court, Christine Mazzola Daher +17
We use time-resolved spectra from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) to examine the distribution of radial velocity (RV) variations in 249 stars id…
Science with the Ultraviolet Explorer (UVEX)
S. R. Kulkarni, Fiona A. Harrison, Brian W. Grefenstette +53
UVEX is a proposed medium class Explorer mission designed to provide crucial missing capabilities that will address objectives central to a broad range of modern astrophysics. The…
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…
The Milky Way Project Second Data Release: Bubbles and Bow Shocks
Tharindu Jayasinghe, Don Dixon, Matthew S. Povich +9
Citizen science has helped astronomers comb through large data sets to identify patterns and objects that are not easily found through automated processes. The Milky Way Project (M…
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…
