Hot Subdwarf All Southern Sky Fast Transit Survey with the Evryscope
Jeffrey K. Ratzloff, Brad N. Barlow, Peter Nemeth +6
We have conducted a survey of candidate hot subdwarf stars in the southern sky searching for fast transits, eclipses, and sinusoidal like variability in the Evryscope light curves.…
EVR-CB-001: An evolving, progenitor, white dwarf compact binary discovered with the Evryscope
Jeffrey K. Ratzloff, Brad N. Barlow, Thomas Kupfer +7
We present EVR-CB-001, the discovery of a compact binary with an extremely low mass () helium core white dwarf progenitor (pre-He WD) and an unseen low mass…
EvryFlare II: Rotation Periods of the Cool Flare Stars in TESS Across Half the Southern Sky
Ward S. Howard, Hank Corbett, Nicholas M. Law +6
We measure rotation periods and sinusoidal amplitudes in Evryscope light curves for 122 two-minute K5-M4 TESS targets selected for strong flaring. The Evryscope array of telescopes…
Variables in the Southern Polar Region Evryscope 2016 Dataset
Jeffrey K. Ratzloff, Henry T. Corbett, Nicholas M. Law +6
The regions around the celestial poles offer the ability to find and characterize long-term variables from ground-based observatories. We used multi-year Evryscope data to search f…
Building the Evryscope: Hardware Design and Performance
Jeffrey K. Ratzloff, Nicholas M. Law, Octavi Fors +4
The Evryscope is a telescope array designed to open a new parameter space in optical astronomy, detecting short timescale events across extremely large sky areas simultaneously. Th…
EvryFlare I: Long-term Evryscope Monitoring of Flares from the Cool Stars Across Half the Southern Sky
Ward S. Howard, Hank Corbett, Nicholas M. Law +5
We search for superflares from 4,068 cool stars in 2+ years of Evryscope photometry, focusing on those with high-cadence data from both Evryscope and TESS. The Evryscope array of s…
