Journal ArticleDOI
Evryscope science: exploring the potential of all-sky gigapixel-scale telescopes
Nicholas M. Law,Octavi Fors,Jeffrey K. Ratzloff,Philip Wulfken,Dustin Kavanaugh,David J. Sitar,Zachary Pruett,Mariah Birchart,Brad N. Barlow,Kipp Cannon,S. Bradley Cenko,B. H. Dunlap,Adam L. Kraus,Thomas J. Maccarone +13 more
TL;DR: The Evryscope as mentioned in this paper is an under-construction 780 MPix telescope which covers 8,660 square degrees in each two-minute exposure; each night, 18,400 square degrees will be continuously observed for an average of approximately 6 hours.
Journal ArticleDOI
Analysis of Helium-rich White Dwarfs Polluted by Heavy Elements in the Gaia Era
S. Coutu,P. Dufour,Pierre Bergeron,Simon Blouin,E. Loranger,Nicole F. Allard,Nicole F. Allard,B. H. Dunlap,B. H. Dunlap +8 more
TL;DR: In this article, a homogeneous analysis of 1023 DBZ/DZ(A) and 319 DQ white dwarf stars taken from the Montreal White Dwarf Database is presented, which represents a significant increase over the previous comprehensive studies on these types of objects.
Journal ArticleDOI
Core crystallization and pile-up in the cooling sequence of evolving white dwarfs
Pier-Emmanuel Tremblay,Gilles Fontaine,Nicola Pietro Gentile Fusillo,B. H. Dunlap,Boris T. Gänsicke,Mark Hollands,J. J. Hermes,Tom Marsh,Elena Cukanovaite,Tim Cunningham +9 more
TL;DR: In this article, the authors report the presence of a pile-up in the cooling sequence of evolving white dwarfs within 100 parsecs of the Sun, determined using photometry and parallax data from the Gaia satellite.
