Anti-Correlation of the Near-Infrared and X-Ray Variations of the Microquasar GRS 1915+105 in Soft State
Akira Arai, Makoto Uemura, Mahito Sasada +21
We report detailed, long term near-infrared (NIR) light curves of GRS 1915+105 in 2007-2008, covering its long "soft state" for the first time. From our NIR monitoring and the X-ra…
Resolved 24.5 micron emission from massive young stellar objects
W. J. de Wit, M. G. Hoare, T. Fujiyoshi +8
Massive young stellar objects (MYSO) are surrounded by massive dusty envelopes. Our aim is to establish their density structure on scales of ~1000 AU, i.e. a factor 10 increase in…
A red supergiant nebula at 25 micron: arcsecond scale mass-loss asymmetries of mu Cep
W. J. de Wit, R. D. Oudmaijer, T. Fujiyoshi +8
We present diffraction limited (0.6") 24.5micron Subaru/COMICS images of the red supergiant mu Cep. We report the detection of a circumstellar nebula, that was not detected at shor…
Testing the External Shock Model of Gamma-Ray Bursts using the Late-Time Simultaneous Optical and X-ray Afterglows
Yuji Urata, Ryo Yamazaki, Takanori Sakamoto +21
We study the ``normal'' decay phase of the X-ray afterglows of gamma-ray bursts (GRBs), which follows the shallow decay phase, using the events simultaneously observed in the R-ban…
The Asymmetric Thermal Emission of Protoplanetary Disk Surrounding HD 142527 Seen by Subaru/COMICS
Hideaki Fujiwara, Mitsuhiko Honda, Hirokazu Kataza +8
Mid-infrared (MIR) images of the Herbig Ae star HD 142527 were obtained at 18.8 and 24.5 micron with the Subaru/COMICS. Bright extended arc-like emission (outer disk) is recognized…
