Understanding Accretion Variability Through TESS Observations of Taurus
Connor E. Robinson, Catherine C. Espaillat, Joseph E. Rodriguez
Interpreting the short-timescale variability of the accreting, young, low-mass stars known as Classical T Tauri stars remains an open task. Month-long, continuous light curves from…
Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle
Maximilian N. Günther, David A. Berardo, Elsa Ducrot +37
New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 (scallop shells) and TESS (complex…
Occultations from an active accretion disk in a 72 day detached post-Algol system detected by K2
G. Zhou, S. Rappaport, L. Nelson +28
Disks in binary systems can cause exotic eclipsing events. MWC 882 (BD-22 4376, EPIC 225300403) is such a disk-eclipsing system identified from observations during Campaign 11 of t…
Identification of Young Stellar Variables with KELT for K2 I: Campaign 13 Taurus Dippers and Rotators
Joseph E. Rodriguez, Megan Ansdell, Ryan J. Oelkers +13
One of the most well-studied young stellar associations, Taurus-Auriga, will be observed by the extended Kepler mission, K2, in the spring of 2017. K2 Campaign 13 (C13) will be a u…
The transiting dust clumps in the evolved disk of the Sun-like UXor RZ Psc
Grant M. Kennedy, Matthew A. Kenworthy, Joshua Pepper +4
RZ Psc is a young Sun-like star, long associated with the UXor class of variable stars, which is partially or wholly dimmed by dust clumps several times each year. The system has a…
Absolute dimensions of the eccentric eclipsing binary V541 Cygni
G. Torres, C. D. McGruder, R. J. Siverd +6
We report new spectroscopic and photometric observations of the main-sequence, detached, eccentric, double-lined eclipsing binary V541 Cyg (P = 15.34 days, e = 0.468). Using these…
Photometric Variability of the Be Star Population
Jonathan Labadie-Bartz, Joshua Pepper, M. Virginia McSwain +11
Be stars have generally been characterized by the emission lines in their spectra, and especially the time variability of those spectroscopic features. They are known to also exhib…
DM Ori: A Young Star Occulted by a Disturbance in its Protoplanetary Disk
Joseph E. Rodriguez, Keivan G. Stassun, Phillip Cargile +15
In some planet formation theories, protoplanets grow gravitationally within a young star's protoplanetary disk, a signature of which may be a localized disturbance in the disk's ra…
An Extreme Analogue of Aurigae: An M-giant Eclipsed Every 69 Years by a Large Opaque Disk Surrounding a Small Hot Source
Joseph E. Rodriguez, Keivan G. Stassun, Michael B. Lund +10
We present TYC 2505-672-1 as a newly discovered and remarkable eclipsing system comprising an M-type red giant that undergoes a ~3.45 year long, near-total eclipse (depth of ~4.5 m…
Recurring Occultations of RW Aurigae by Coagulated Dust in the Tidally Disrupted Circumstellar Disk
Joseph E. Rodriguez, Phillip A. Reed, Robert J. Siverd +7
We present photometric observations of RW Aurigae, a Classical T Tauri system, that reveal two remarkable dimming events. These events are similar to that which we observed in 2010…
First Results from the Disk Eclipse Search with KELT (DESK) Survey
Joseph E. Rodriguez, Joshua Pepper, Keivan G. Stassun
Using time-series photometry from the Kilodegree Extremely Little Telescope (KELT) exoplanet survey, we are looking for eclipses of stars by their protoplanetary disks, specificall…
New Red Jewels in Coma Berenices
Ryan C. Terrien, Suvrath Mahadevan, Rohit Deshpande +18
We have used Sloan Digital Sky Survey-III (SDSS-III) Apache Point Observatory Galactic Evolution Experiment (APOGEE) radial velocity observations in the near-infrared -band to e…
Occultation of the T Tauri Star RW Aurigae A by its Tidally Disrupted Disk
Joseph E. Rodriguez, Joshua Pepper, Keivan G. Stassun +4
RW Aur A is a classical T Tauri star, believed to have undergone a reconfiguration of its circumstellar environment as a consequence of a recent fly-by of its stellar companion, RW…
