Hubble Space Telescope Snapshot Survey for Resolved Companions of Galactic Cepheids: Final Results
Nancy Remage Evans, H. Moritz Guenther, Howard E. Bond +13
Cepheids in multiple systems provide information on the outcome of the formation of massive stars. They can also lead to exotic end-stage objects. This study concludes our survey o…
The Orbit of the Close Companion of Polaris: Hubble Space Telescope Imaging 2007 to 2014
Nancy Remage Evans, Margarita Karovska, Howard E. Bond +6
As part of a program to determine dynamical masses of Cepheids, we have imaged the nearest and brightest Cepheid, Polaris, with the Hubble Space Telescope Wide Field Planetary Came…
Hubble Space Telescope: Snapshot Survey for Resolved Companions of Galactic Cepheids
Nancy Remage Evans, Howard E. Bond, Gail H. Schaefer +4
We have conducted an imaging survey with the Hubble Space Telescope Wide Field Camera~3 (WFC3) of 70 Galactic Cepheids, typically within 1~kpc, with the aim of finding resolved phy…
Resolved Companions of Cepheids: Testing the Candidates with X-Ray Observations
Nancy Remage Evans, Ignazio Pillitteri, Scott Wolk +7
We have made {\it XMM-Newton\/} observations of 14 Galactic Cepheids that have candidate resolved (5$\arcsec$) companion stars based on our earlier {\it HST\/} WFC3 imaging s…
X-ray Detection of the Cluster Containing the Cepheid S Mus
Nancy Remage Evans, Ignazio Pillitteri, Scott J. Wolk +7
The galactic Cepheid S Muscae has recently been added to the important list of Cepheids linked to open clusters, in this case the sparse young cluster ASCC 69. Low-mass members of…
Binary Cepheids: Separations and Mass Ratios in Binaries
Nancy Remage Evans, Howard E. Bond, Gail H. Schaefer +3
Deriving the distribution of binary parameters for a particular class of stars over the full range of orbital separations usually requires the combination of results from many diff…
