Unveiling the Infrared Excess of SIPS J2045-6332: Evidence for a Young Stellar Object with Potential Low-Mass Companion
Michiharu Hyogo, Thomas P. Bickle, Joseph R. Biggs +20
The Disk Detective project, a citizen science initiative, aims to identify circumstellar discs around stars by detecting objects with infrared (IR) excess using data from the Wide-…
Stable Coronal X-Ray Emission Over Twenty Years of XZ Tau
Steven M. Silverberg, Hans Moritz Guenther, Pragati Pradhan +3
XZ Tau AB is a frequently observed binary YSO in the Taurus Molecular Cloud; XZ Tau B has been classified as an EXOr object. We present new Chandra/HETG-ACIS-S observations of XZ T…
The Mass-Temperature Relation for B and Early A Stars Based on IUE Spectra of Detached Eclipsing Binaries
Nancy Remage Evans, Mckenzie G. Ferrari, Joanna Kuraszkiewicz +4
Ultraviolet spectra were taken of 25 Detached Eclipsing Binaries (DEBs) with spectral types O, B, and early A with the International Ultraviolet Explorer (IUE) satellite in the 115…
Chandra Observations of Six Peter Pan Disks: Diversity of X-ray-driven Internal Photoevaporation Rates Doesn't Explain Their Rare Longevity
E. Laos, J. P. Wisniewski, M. J. Kuchner +6
We present Chandra X-ray observations of 6 previously-identified Peter Pan objects, rare 40 Myr systems with evidence of primordial disk retention. We observe X-ray luminosities (0…
Disks in Nearby Young Stellar Associations Found Via Virtual Reality
Susan Higashio, Marc J. Kuchner, Steven M. Silverberg +24
The Disk Detective citizen science project recently released a new catalog of disk candidates found by visual inspection of images from NASA's Wide-Field Infrared Survey Explorer (…
What's Behind the Elephant's Trunk? Identifying Young Stellar Objects on the Outskirts of IC1396
Steven M. Silverberg, Hans Moritz Guenther, Jinyoung Serena Kim +2
Empirically, the estimated lifetime of a typical protoplanetary disk is Myr. However, the disk lifetimes required to produce a variety of observed exoplanetary systems may…
Discovery of a Nearby Young Brown Dwarf Disk
M. C. Schutte, K. D. Lawson, J. P. Wisniewski +15
We report the discovery of the youngest brown dwarf with a disk at 102 pc from the Sun, WISEA~J120037.79-784508.3 (W1200-7845), via the Disk Detective citizen science project. We e…
Peter Pan Disks: Long-lived Accretion Disks Around Young M Stars
Steven M. Silverberg, John P. Wisniewski, Marc J. Kuchner +12
WISEA J080822.18-644357.3, an M star in the Carina association, exhibits extreme infrared excess and accretion activity at an age greater than the expected accretion disk lifetime.…
The First Brown Dwarf Discovered by the Backyard Worlds: Planet 9 Citizen Science Project
Marc J. Kuchner, Jacqueline K. Faherty, Adam C. Schneider +9
The Wide-field Infrared Survey Explorer (WISE) is a powerful tool for finding nearby brown dwarfs and searching for new planets in the outer solar system, especially with the incor…
Kepler Flares IV: A Comprehensive Analysis of the Activity of the dM4e Star GJ 1243
Steven M. Silverberg, Adam F. Kowalski, James R. A. Davenport +3
We present a comprehensive study of the active dM4e star GJ 1243. We use previous observations and ground-based echelle spectroscopy to determine that GJ 1243 is a member of the Ar…
Kepler Flares II: The Temporal Morphology of White-Light Flares on GJ 1243
James R. A. Davenport, Suzanne L. Hawley, Leslie Hebb +12
We present the largest sample of flares ever compiled for a single M dwarf, the active M4 star GJ 1243. Over 6100 individual flare events, with energies ranging from to $…
