A search for radio pulsations from neutron star companions of four subdwarf B stars.

COENEN T., VAN LEEUWEN J. and STAIRS I.H.

Abstract (from CDS):

We searched for radio pulsations from the potential neutron star binary companions to subdwarf B stars HE0532-4503, HE0929-0424, TONS183 and PG1232-136. Optical spectroscopy of these subdwarfs has indicated they orbit a companion in the neutron star mass range. These companions are thought to play an important role in the poorly understood formation of subdwarf B stars. Using the Green Bank Telescope we searched down to mean flux densities as low as 0.2mJy, but no pulsed emission was found. We discuss the implications for each system.
