Massive Variability Searches: The Past, Present and Future Massive Variability Searches
Bohdan Paczynski
Many decades ago a search for variable stars was one of the main areas of astrophysical research. Such searches, conducted with CCD detectors rather than with photographic plates,…
Optical Flashes Preceding GRBs
Bohdan Paczynski
Only one optical flash associated with a gamma-ray burst has been detected so far by ROTSE. There are also upper limits obtained by several groups for several bursts. Recent model…
Monitoring Variability of the Sky
Bohdan Paczynski
Variability in the sky has been known for centuries, even millennia, but our knowledge of it is very incomplete even at the bright end. Current technology makes it possible to buil…
Can HST Measure the Mass of the Isolated Neutron Star RX J185635-3754 ?
Bohdan Paczynski
In June 2003 the isolated neutron star RX J185635-3754 will pass within 0.3'' of a 26.5 mag star, changing its position by about 0.6 mas. The displacement, caused by gravitational…
Gamma-Ray Bursts at Low Redshift
Bohdan Paczynski
Long duration gamma-ray bursts (GRB) are at cosmological distance, they appear to be located near star forming regions, and are likely associated with some type of supernovae. They…
The Distance to the Magellanic Clouds
Bohdan Paczynski
The distance to LMC and SMC is a subject of controversy, with the difference between the extreme values in distance moduli exceeding 0.5 mag. While currently the best calibrated me…
