A Dataset for Exploring Stellar Activity in Astrometric Measurements from SDO Images of the Sun
Warit Wijitworasart, Zoe de Beurs, Andrew Vanderburg
We present a dataset for investigating the impact of stellar activity on astrometric measurements using NASA's Solar Dynamics Observatory (SDO) images of the Sun. The sensitivity o…
Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network
T. W. Milbourne, D. F. Phillips, N. Langellier +21
State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
A tidally tilted sectoral dipole pulsation mode in the eclipsing binary TIC 63328020
S. A. Rappaport, D. W. Kurtz, G. Handler +13
We report the discovery of the third tidally tilted pulsator, TIC 63328020. Observations with the TESS satellite reveal binary eclipses with an orbital period of 1.1057 d, and …
TIC 168789840: A Sextuply-Eclipsing Sextuple Star System
Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport +48
We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three…
The K2 M67 Study: Precise Mass for a Turnoff Star in the Old Open Cluster M67
Eric L. Sandquist, David W. Latham, Robert. D. Mathieu +8
We present a study of the bright detached eclipsing main sequence binary WOCS 11028 (Sanders 617) in the open cluster M67. Although the binary has only one eclipse per orbital cycl…
Eclipsing binaries in the open cluster Ruprecht 147. III: The triple system EPIC 219552514 at the main-sequence turnoff
Guillermo Torres, Andrew Vanderburg, Jason L. Curtis +3
Spectroscopic observations are reported for the 2.75 day, double-lined, detached eclipsing binary EPIC 219552514 located at the turnoff of the old nearby open cluster Ruprecht 147.…
Orbital Parameter Determination for Wide Stellar Binary Systems in the Age of Gaia
Logan A. Pearce, Adam L. Kraus, Trent J. Dupuy +4
The orbits of binary stars and planets, particularly eccentricities and inclinations, encode the angular momentum within these systems. Within stellar multiple systems, the magnitu…
Eclipsing binaries in the open cluster Ruprecht 147. II: EPIC 219568666
Guillermo Torres, Andrew Vanderburg, Jason L. Curtis +7
We report our spectroscopic monitoring of the detached, grazing, and slightly eccentric 12-day double-lined eclipsing binary EPIC 219568666 in the old nearby open cluster Ruprecht…
Eclipsing binaries in the open cluster Ruprecht 147. I: EPIC 219394517
Guillermo Torres, Jason L. Curtis, Andrew Vanderburg +2
Eclipsing binaries in star clusters offer more stringent tests of stellar evolution theory than field binaries because models must not only match the binary properties, but also th…
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…
The K2 M67 Study: A Curiously Young Star in an Eclipsing Binary in an Old Open Cluster
Eric L. Sandquist, Robert D. Mathieu, Samuel N. Quinn +16
We present an analysis of a slightly eccentric (), partially eclipsing long-period ( d) main sequence binary system (WOCS 12009, Sanders 1247) in the benchmark o…
The Mysterious Dimmings of the T Tauri Star V1334 Tau
Joseph E. Rodriguez, George Zhou, Phillip A. Cargile +35
We present the discovery of two extended 0.12 mag dimming events of the weak-lined T-Tauri star V1334. The start of the first event was missed but came to an end in late 2003…
