Modeling the SS 433 Jet Bends
Herman L. Marshall, Claude R. Canizares, Norbert S. Schulz +3
We fit Chandra HETGS data obtained for the unusual X-ray binary SS 433. While line strengths and continuum levels hardly change, the jet Doppler shifts show aperiodic variations th…
Binary central stars of PN discovered through photometric variability. I. What we know and what we would like to find out
Orsola De Marco, Todd C. Hillwig, A. J. Smith
Shaping axi-symmetric planetary nebulae is easier if a companion interacts with a primary at the top of the asymptotic giant branch. To determine the impact of binarity on planetar…
Dynamical Masses for the Large Magellanic Cloud Massive Binary System [L72] LH 54-425
S. J. Williams, D. R. Gies, T. J. Henry +8
We present results from an optical spectroscopic investigation of the massive binary system [L72] LH~54-425 in the LH 54 OB association in the Large Magellanic Cloud. We revise the…
Stellar Wind Variations During the X-ray High and Low States of Cygnus X-1
D. R. Gies, C. T. Bolton, R. M. Blake +10
We present results from Hubble Space Telescope UV spectroscopy of the massive X-ray binary system, HD226868 = Cyg X-1. The spectra were obtained at both orbital conjunction phases…
Spectroscopic Observations of the Mass Donor Star in SS 433
Todd C. Hillwig, Douglas R. Gies
The microquasar SS 433 is an interacting massive binary consisting of an evolved mass donor and a compact companion that ejects relativistic jets. The mass donor was previously ide…
A Spectroscopic Study of Mass Outflows in the Interacting Binary RY Scuti
E. D. Grundstrom, D. R. Gies, T. C. Hillwig +5
The massive interacting binary RY Scuti is an important representative of an active mass-transferring system that is changing before our eyes and which may be an example of the for…
