Evidence for Pulsation-Driven Mass Loss from delta Cephei
M. Marengo, N. R. Evans, L. D. Matthews +7
We found the first direct evidence that the Cepheid class namesake, delta Cephei, is currently losing mass. These observations are based on data obtained with the Spitzer Space Tel…
New Evidence for Mass Loss from delta Cephei from HI 21-cm Line Observations
L. D. Matthews, M. Marengo, N. R. Evans +1
Recently published Spitzer observations of the classical Cepheid archetype delta Cephei revealed an extended dusty nebula surrounding this star and its hot companion. The infrared…
An Infrared Nebula Associated with Delta Cephei: Evidence of Mass Loss?
M. Marengo, N. R. Evans, P. Barmby +7
We present the discovery of an infrared nebula around the Cepheid prototype delta Cephei and its hot companion HD 213307. Large scale (~2.1x10^4 AU) nebulosity is detected at 5.8,…
Cepheid investigations using the Kepler space telescope
R. Szabó, L. Szabados, C. -C. Ngeow +35
We report results of initial work done on selected candidate Cepheids to be observed with the Kepler space telescope. Prior to the launch 40 candidates were selected from previous…
