The Evryscope (“wide-seer”) is an array of telescopes pointed at every part of the accessible sky simultaneously and continuously, together forming a gigapixel-scale telescope monitoring an overlapping 8,000 square degree field every 2 minutes.Looking for info on the Proxima superflare? Here’s our public information page.Funded by NSF/ATI and NSF/CAREER, and operating in Chile since 2016 and California since 2019, the two Evryscopes together give two-minute-cadence coverage of over 16,000 square degrees. Find the details of the Evryscope design in this paper, which includes a comprehensive look at our science plans for the system. Interested in collaboration to use Evryscope data? Please contact Nick Law (nmlaw-at-physics-dot-unc-dot-edu).

New papers exploring hot-subdwarf planets and common-envelope evolution

  • December 1st, 2019

Two new papers from the Evryscope team detail the results of the Evryscope hot subdwarf binary and planet transit surveys:

Hot Subdwarf All Southern Sky Fast Transit Survey with the Evryscope (AJ 2020, in press)
Ratzloff, Jeffrey K.; Barlow, Brad N.; Nemeth, Peter; Corbett, Henry T.; Walser, Stephen; Galliher, Nathan W.; Glazier, Amy; Howard, Ward S.; Law, Nicholas M.

EVR-CB-001: An Evolving, Progenitor, White Dwarf Compact Binary Discovered with the Evryscope (ApJ 2019, 883 51R)
Ratzloff, Jeffrey K.; Barlow, Brad N.; Kupfer, Thomas; Corcoran, Kyle A.; Geier, Stephan; Bauer, Evan; Corbett, Henry T.; Howard, Ward S.; Glazier, Amy; Law, Nicholas M.

Several more results from this survey, which has found dozens of multiple-star systems in this mysterious phase of stellar evolution, are under review.
