An Eclipsing Binary Comprising Two Active Red Stragglers of Identical Mass and Synchronized Rotation: A Post-Mass-Transfer System or Just Born That Way?
Keivan G. Stassun, Guillermo Torres, Marina Kounkel +7
We report the discovery of 2M0056-08 as an equal-mass eclipsing binary (EB), comprising two red straggler stars (RSSs) with an orbital period of 33.9 d. Both stars have masses of 1…
WIYN Open Cluster Study. LXXXVII. HST Ultraviolet Detection of Hot White Dwarf Companions to Blue Lurkers in M67
Andrew C. Nine, Robert D. Mathieu, Natalie M. Gosnell +1
We present the results of our Hubble Space Telescope far-ultraviolet survey of the blue lurkers (BLs) in M67. We find evidence for two white dwarf companions among the BLs that are…
WOCS 4540: Detailed Analysis of a Very Long Orbital Period Blue Straggler
Meng Sun, Robert D. Mathieu
WOCS 4540 is the longest orbital period ( days) blue straggler (BSS) - white dwarf (WD) pair in the old open cluster NGC 188 . It also contains one of the most lu…
Evolved Eclipsing Binaries and the Age of the Open Cluster NGC 752
Eric L. Sandquist, Andrew J. Buckner, Matthew D. Shetrone +8
We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 day binary DS An…
2M17091769+3127589: a mass-transfer binary with an extreme mass ratio
Annaliese Miller, Marina Kounkel, Meng Sun +5
We present the orbital solution of a peculiar double-lined spectroscopic and eclipsing binary system, 2M17091769+3127589. This solution was obtained by a simultaneous fit of both A…
Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. III. Constraints from a subgiant
K. Brogaard, F. Grundahl, E. L. Sandquist +18
Models of stellar structure and evolution can be constrained using accurate measurements of the parameters of eclipsing binary members of open clusters. Multiple binary stars provi…
