Age Discrepancy in Three Galactic Cepheid Binaries
Sashwat Prasadh, Hilding R. Neilson, Nancy Remage Evans
SV Per, RW Cam, and KN Cen are Galactic classical Cepheids found in binary systems along with B-type companions. Each system exhibits an ``apparent age discrepancy", where the Ceph…
The Mass-Temperature Relation for B and Early A Stars Based on IUE Spectra of Detached Eclipsing Binaries
Nancy Remage Evans, Mckenzie G. Ferrari, Joanna Kuraszkiewicz +4
Ultraviolet spectra were taken of 25 Detached Eclipsing Binaries (DEBs) with spectral types O, B, and early A with the International Ultraviolet Explorer (IUE) satellite in the 115…
Challenges in Cepheid Evolution and Pulsation Modeling
Joyce A. Guzik, Jason Jackiewicz, Nancy R. Evans
Cepheids have long been used as standard candles to determine distances around the Milky Way and to nearby galaxies. A discrepancy still remains for Hubble Constant determinations…
First Detection of Radio Emission Associated with a Classical Cepheid
L. D. Matthews, N. R. Evans, M. P. Rupen
We report the detection of 15 GHz radio continuum emission associated with the classical Cepheid variable star delta Cephei based on observations with the Karl G. Jansky Very Large…
Non-thermal -rays from pulsation-driven shocks in Cepheids
Federico Fraschetti, Konstantina Anastasopoulou, Jeremy J. Drake +1
Rapid X-ray phase-dependent flux enhancement in the archetype classical Cepheid star ~Cep was observed by XMM-Newton and Chandra. We jointly analyse thermal and non-thermal comp…
X-rays in Cepheids: Identifying Low-Mass Companions of Intermediate-Mass Stars
Nancy Remage Evans, Scott Engle, Ignazio Pillitteri +12
X-ray observations have been made of a sample of 20 classical Cepheids, including two new observations (Polaris and {\it l} Car) reported here. The occurrence of X-ray flux around…
