Proposal Title: Searching for a radio pulsar around an extremely low­mass white dwarf
ABSTRACT:
Low­mass white dwarfs are the prototypical companions of highly recycled millisecond pulsars. Both are the result
of a low­mass X­ray binary phase in which much of the white­dwarf envelope is transferred to the neutron star,
spinning up the latter. We here request a total of 2.5 hours to search for radio pulsations from the companion of a
newly discovered extremely low­mass white dwarf. The discovery of a pulsar companion would be interesting for
constraining neutron­star masses, binary evolution models and binary formation rates.
