Global Disk Oscillations in Binary Be Stars
Finny Oktariani, Atsuo T. Okazaki
We study the effects of the tidal interaction with the companion, via orbital separation and binary mass ratio, on the global one-armed oscillation modes in disks around binary Be…
A new approach for probing circumbinary disks
Kimitake Hayasaki, Atsuo T. Okazaki
Circumbinary disks are considered to exist in a wide variety of astrophysical objects, e.g., young binary stars, protoplanetary systems, and massive binary black hole systems in ac…
Modeling the RXTE light curve of Carinae from a 3-D SPH simulation of its binary wind collision
A. T. Okazaki, S. P. Owocki, C. M. Russell +1
The very massive star system Carinae exhibits regular 5.54-year (2024-day) period disruptive events in wavebands ranging from the radio to X-ray. There is a growing consensus t…
3-D SPH simulations of colliding winds in eta Carinae
Atsuo T. Okazaki, Stanley P. Owocki, Christopher M. P. Russell +1
We study colliding winds in the superluminous binary eta Carinae by performing three-dimensional, Smoothed Particle Hydrodynamics (SPH) simulations. For simplicity, we assume both…
Tidal Interactions of Red Giants with Environment Stars in Globular Clusters
Shimako Yamada, Atsuo T. Okazaki, Masayuki Y. Fujimoto
We investigate the tidal interactions of a red giant with a main sequence in the dense stellar core of globular clusters by Smoothed Particle Hydrodynamics method. Two models of $0…
