Rotation periods of TESS Objects of Interest from the Magellan-TESS Survey with multiband photometry from Evryscope and TESS
Ward S. Howard, Johanna Teske, Hank Corbett +8
Stellar RV jitter due to surface activity may bias the RV semi-amplitude and mass of rocky planets. The amplitude of the jitter may be estimated from the uncertainty in the rotatio…
Revisiting the HD 21749 Planetary System with Stellar Activity Modeling
Tianjun Gan, Sharon Xuesong Wang, Johanna K. Teske +26
HD 21749 is a bright ( mag) K dwarf at 16 pc known to host an inner terrestrial planet HD 21749c as well as an outer sub-Neptune HD 21749b, both delivered by TESS. Follow-up…
Orbital Foregrounds for Ultra-Short Duration Transients
Hank Corbett, Nicholas M. Law, Alan Vasquez Soto +7
Reflections from objects in Earth orbit can produce sub-second, star-like optical flashes similar to astrophysical transients. Reflections have historically caused false alarms for…
EvryFlare III: Temperature Evolution and Habitability Impacts of Dozens of Superflares Observed Simultaneously by Evryscope and TESS
Ward S. Howard, Hank Corbett, Nicholas M. Law +8
Superflares may provide the dominant source of biologically relevant UV radiation to rocky habitable zone M-dwarf planets (M-Earths), altering planetary atmospheres and conditions…
EVR-CB-004: An Inflated Hot Subdwarf O star + Unseen WD Companion in a Compact Binary Discovered with the Evryscope
Jeffrey K. Ratzloff, Thomas Kupfer, Brad N. Barlow +10
We present the discovery of EVR-CB-004, a close binary with a remnant stellar core and an unseen white dwarf companion. The analysis in this work reveals the primary is potentially…
Multi-wavelength Photometry and Progenitor Analysis of the Nova V906 Car
Jerrick Wee, Nadejda Blagorodnova, Bryan Edward Penprase +12
We present optical and infrared photometry of the classical nova V906 Car, also known as Nova Car 2018 and ASASSN-18fv, discovered by ASASS-SN survey on 16.32 March 2018 UT (MJD 58…
