K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova

G. Dimitriadis, R. J. Foley, A. Rest +145

We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…

Photodynamical analysis of the triply eclipsing hierarchical triple system EPIC 249432662

T. Borkovits, S. Rappaport, T. Kaye +16

Using Campaign 15 data from the K2 mission, we have discovered a triply-eclipsing triple star system: EPIC 249432662. The inner eclipsing binary system has a period of 8.23 days, w…

Precovery of TESS Single Transits with KELT

Xinyu Yao, Joshua Pepper, B. Scott Gaudi +12

During the TESS prime mission, 74% of the sky area will only have an observational baseline of 27 days. For planets with orbital periods longer than 13.5 days, TESS can only captur…

An Estimate of the Yield of Single-Transit Planetary Events from the Transiting Exoplanet Survey Satellite

Steven Villanueva, Diana Dragomir, B. Scott Gaudi

We present a semi-analytic estimate of the expected yield of single-transit planets from the Transiting Exoplanet Survey Satellite (TESS). We use the TESS Candidate Target List 6 (…
