Variable Sodium Absorption in a Low-Extinction Type Ia Supernova

Joshua D. Simon, Avishay Gal-Yam, Orly Gnat +18

Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but…

Nebular Phase Observations of the Type Ib Supernova 2008D/X-ray Transient 080109: Side-Viewed Bipolar Explosion

Masaomi Tanaka, Masayuki Yamanaka, Keiichi Maeda +11

We present optical spectroscopic and photometric observations of supernova (SN) 2008D, associated with the luminous X-ray transient 080109, at >300 days after the explosion (nebula…

Low metallicity and ultra-luminous X-ray sources in the Cartwheel galaxy

M. Mapelli, M. Colpi, L. Zampieri

Low-metallicity (Z <~ 0.05 Zsun) massive (>~40 Msun) stars might end their life by directly collapsing into massive black holes (BHs, 30 <~ m_BH/Msun <~ 80). More than ~10^5 massiv…

Tidal disruption of small satellites orbiting black holes

C. Germana, U. Kostic, A. Cadez +1

Low Mass X-ray Binaries (LMXBs) with either a black hole or a neutron star show power spectra characterised by Quasi Periodic Oscillations (QPOs). Twin peak high frequency QPOs are…

Tidal effects on small bodies by massive black holes

U. Kostic, A. Cadez, M. Calvani +1

The compact radio source Sagittarius A (Sgr A) at the centre of our Galaxy harbours a supermassive black hole, whose mass has been measured from stellar orbital motions. Sgr A is t…
