Observational Appearance of Relativistic, Spherically Symmetric Massive Winds

N. Sumitomo, S. Nishiyama, C. Akizuki +2

The photon mean free path in a relativistically moving medium becomes long in the down-stream direction while short in the up-stream direction. As a result, the observed optical de…

Optical light curves of RS Oph (2006) and hydrogen burning turnoff

Izumi Hachisu, Mariko Kato, Seiichiro Kiyota +11

We report a coordinated multi-band photometry of the RS Oph 2006 outburst and highlight the emission line free y-band photometry that shows a mid-plateau phase at y ~ 10.2 mag from…
