Next: Black Hole Creation in Up: No Title Previous: Periodic radiosource LSI+61 303 . Several candidates for binary BH with optical companions are known at present (see van Paradijs and McClintock, 1993,[ 208 ] for a review). They must be products of the evolution   of binary systems with massive companions. Lipunov et al. (1994b)[ 124 ] calculated the expected number of BH+PSR binaries following directly from the modern scenario of binary star evolution using the Scenario Machine. ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...
