Black Widow Stars That Consume & Destroy Their Partners

Astronomer Roger Romani, Ph.D., of Stanford University, will discuss Black Widow Stars That Consume and Destroy Their Partners, an illustrated, non-technical lecture Wednesday, January 22, at 7:00 p.m. in the Smithwick Theatre at Foothill College in Los Altos Hills. Admission is free and the public is invited. Seating is on a first-come, first-served basis.

Dr. Romani is an astrophysicist interested in neutron stars, black holes and other relativistic, high energy sources —where density, gravitational field and, often, magnetic field reach their maximum measured values.

NASA’s Fermi Gamma-ray Space Telescope has revealed a violent high-energy universe full of stellar explosions, black hole jets, and pulsing stars. Dr. Romani will describe the quest to discover the true nature of the most puzzling of these gamma-ray sources. Several turn out to be a star corpse called a ‘black widow’ pulsar.  When a massive star dies, it leaves a collapsed remnant called a neutron star. When a star corpse has a companion star, it can be reanimated by material from the companion.  The revived corpse then begins to vaporize its mate.

The lecture is free; however, there is a charge of $3 for parking and exact change is appreciated.

Parking lots 1, 7 and 8 provide stair and no-stair access to the Smithwick Theater.
