Deep HST Imaging in NGC 6397: Stellar Dynamics
J. S. Heyl, H. Richer, J. Anderson +9
Multi-epoch observations with ACS on HST provide a unique and comprehensive probe of stellar dynamics within NGC 6397. We are able to confront analytic models of the globular clust…
AT Cnc: A Second Dwarf Nova with a Classical Nova Shell
Michael M. Shara, Trisha Mizusawa, Peter Wehinger +5
We are systematically surveying all known and suspected Z Cam-type dwarf novae for classical nova shells. This survey is motivated by the discovery of the largest known classical n…
The Inter-Eruption Timescale of Classical Novae from Expansion of the Z Camelopardalis Shell
Michael M. Shara, Trisha Mizusawa, David Zurek +3
The dwarf nova Z Camelopardalis is surrounded by the largest known classical nova shell. This shell demonstrates that at least some dwarf novae must have undergone classical nova e…
A multi-wavelength survey of NGC\,6752: X-ray counterparts, two new dwarf novae, and a core-collapsed radial profile
G. S. Thomson, C. Knigge, A. Dieball +6
We present the results of a multi-wavelength (FUV to I-band) survey of the stellar populations of the globular cluster NGC 6752, using STIS, ACS and WFC3 on board the Hubble Space…
Searching for Wolf-Rayet Stars in M101
J. L. Bibby, P. A. Crowther, A. F. J. Moffat +3
Wolf-Rayet (WR) stars are the evolved descendants of massive O-type stars and are considered to be progenitor candidates for Type Ib/c core-collapse supernovae (SNe). Recent result…
GK Per (Nova Persei 1901): HST Imagery and Spectroscopy of the Ejecta, and First Spectrum of the Jet-Like Feature
Michael M. Shara, David Zurek, Orsola De Marco +3
We have imaged the ejecta of GK Persei (Nova Persei 1901 A.D.) with the Hubble Space Telescope (HST), revealing hundreds of cometary-like structures. One or both ends of the struct…
