Discovery of extraordinary X-ray emission from magnetospheric interaction in the unique binary stellar system Lupi
B. Das, V. Petit, Y. Nazé +12
We report detailed X-ray observations of the unique binary system Lupi, the only known short-period binary consisting of two magnetic early-type stars. The components have comp…
NICER X-ray Observations of Eta Carinae During its Most Recent Periastron Passage
David Espinoza-Galeas, Michael Francis Corcoran, Kenji Hamaguchi +12
We report high-precision X-ray monitoring observations in the 0.4-10 keV band of the luminous, long-period colliding-wind binary Eta Carinae up to and through its most recent X-ray…
The RS CVn type star GT Mus shows most energetic X-ray flares throughout the 2010s
Ryo Sasaki, Yohko Tsuboi, Wataru Iwakiri +14
We report that the RS CVn-type star GT Mus (HR 4492, HD 101379 + HD 101380) was the most active star in the X-ray sky in the last decade in terms of the scale of recurrent energeti…
Non-thermal X-rays from Colliding Wind Shock Acceleration in the Massive Binary Eta Carinae
Kenji Hamaguchi, Michael F. Corcoran, Julian M. Pittard +9
Cosmic-ray acceleration has been a long-standing mystery and despite more than a century of study, we still do not have a complete census of acceleration mechanisms. The collision…
Hydrodynamic and radiative transfer modeling of X-ray emission from colliding WR winds: WR 140 & the Galactic center
Christopher M. P. Russell, Michael F. Corcoran, Jorge Cuadra +6
Colliding Wolf-Rayet (WR) winds produce thermal X-ray emission widely observed by X-ray telescopes. In wide WR+O binaries, such as WR 140, the X-ray flux is tied to the orbital pha…
Suzaku Monitoring of Hard X-ray Emission from Eta Carinae over a Single Binary Orbital Cycle
Kenji Hamaguchi, Michael F. Corcoran, Hiromitsu Takahashi +6
The Suzaku X-ray observatory monitored the supermassive binary system Eta Carinae 10 times during the whole 5.5 year orbital cycle between 2005-2011. This series of observations pr…
3D Hydrodynamic & Radiative Transfer Models of X-ray Emission from Colliding Wind Binaries
Christopher M. P. Russell, Atsuo T. Okazaki, Stanley P. Owocki +3
Colliding wind binaries (CWBs) are unique laboratories for X-ray astrophysics. The massive stars in these systems possess powerful stellar winds with speeds up to 3000 km s$^…
Galactic Sources Science With Agile: The Case Of The Carina Region
S. Sabatini, M. Tavani, E. Pian +63
During its first 2 years of operation, the gamma-ray AGILE satellite accumulated an extensive dataset for the Galactic plane. The data have been monitored for transient sources and…
Understanding the X-ray Flaring from Eta Car
A. F. J. Moffat, M. F. Corcoran
We quantify the rapid variations in X-ray brightness ("flares") from the extremely massive colliding wind binary Eta Carinae seen during the past three orbital cycles by RXTE. The…
High energy emission from massive stars: the precocious X-Ray recovery of Eta Carinae after January 2009 minimum
Elena Pian, Sergio Campana, Guido Chincarini +7
We observed the massive binary stellar system of Eta Carinae in the 0.3-10 keV energy range with the X-ray Telescope onboard the Swift satellite during the period 15 December 2008…
Detection of Gamma-ray Emission from the Eta-Carinae Region
M. Tavani, S. Sabatini, E. Pian +63
We present the results of extensive observations by the gamma-ray AGILE satellite of the Galactic region hosting the Carina nebula and the remarkable colliding wind binary Eta Cari…
3D modelling of the colliding winds in Eta Carinae - evidence for radiative inhibition
E. R. Parkin, J. M. Pittard, M. F. Corcoran +2
The X-ray emission from the super-massive star Eta Carinae is simulated using a three dimensional model of the wind-wind collision. In the model the intrinsic X-ray emission is spa…
