  • Millisecond Pulsars: A Decade of Surprise ASP Conference Series, Vol. 72, 1995 AS Fruchter, M. Tavani, and DC Backer, eds. PULSAR ECLIPSE AND COMPANION MASS LOSS D. EICHLER. AND M. GEDALIN Ben-Gurion University, FOB 653, Beer-Sheva, 84105, Israel ABSTRACT Motivations and theories of mass loss from neutron star companions are reviewed. Eclipse mechanisms, and their implications for “measurements” of wind properties are also reviewed, The eclipse data suggests that the mass loss from the companion is much less than needed to account for the observed orbital period derivative. Possibilities are considered that the eclipse is not caused by matter evaporated directly off the companion. INTRODUCTION The discovery of eclipsing pulsars (Fruchter et. al. 1988) generated a great deal of interest in the topic of mass evaporation off companion stars. The general question had been …
