Accretion onto the Companion of Eta Carinae During the Spectroscopic Event: III. the He II 4686 Line [PDF]
, 2006 We continue to explore the accretion model of the massive binary system eta Carinae by studying the anomalously high He II 4686 line. The line appears just before periastron and disappears immediately thereafter.

Morphology of Hydrodynamic Winds: A Study of Planetary Winds in Stellar Environments [PDF]
, 2018 Bathed in intense ionizing radiation, close-in gaseous planets undergo hydrodynamic atmospheric escape, which ejects the upper extent of their atmospheres into the interplanetary medium.

The interaction of multiple stellar winds in stellar clusters: potential flow
, 2018 While several studies have investigated large-scale cluster winds resulting from an intra-cluster interaction of multiple stellar winds, as yet they have not provided details of the bordering flows inside a given cluster.

On the Dynamical Structure of the Jet System in the Disk with the Keplerian Rotation [PDF]
Journal of Astronomy and Space Sciences, 1989 The classical sloar wind theory proposed by Parker(1963) explains well the dynamics of the wind pheonomena such as stellar wind accretion disk. While the stellar wind system like the solar wind has the spherically symmetric wind structure, there are ...

A New Study on a Type Iax Stellar Remnant and its Probable Association with SN 1181
The Astrophysical Journal, 2023 We report observations and modeling of the stellar remnant and presumed double-degenerate merger of Type Iax supernova Pa 30, which is the probable remnant of SN 1181 AD.

Axisymmetric Simulations of Hot Jupiter-Stellar Wind Hydrodynamic Interaction
, 2016 Gas giant exoplanets orbiting at close distances to the parent star are subjected to large radiation and stellar wind fluxes. In this paper, hydrodynamic simulations of the planetary upper atmosphere and its interaction with the stellar wind are carried ...

Halo Emission of the Cat's Eye Nebula, NGC 6543 Shock Excitation by Fast Stellar Winds [PDF]
Journal of Astronomy and Space Sciences, 2002 Images taken with the Chandra X-ray telescope have for the the first time revealed the central, wind-driven, hot bubble (Chu et al. 2001), while Hubble Space Telescope (HST) WFPC2 images of the Cat's Eye nebula, NGC 6543, show that the temperature of the

, 2016 Winds of AGB stars are thought to be driven by a combination of pulsation-induced shock waves and radiation pressure on dust. In dynamic atmosphere and wind models, the stellar pulsation is often simulated by prescribing a simple sinusoidal variation in ...
