Proposal Title: A Search for Radio Pulsations from Isolated Neutron Stars
ABSTRACT:
X-ray surveys have uncovered a new class objects collectively known as \isolated neutron stars". These appear to
be middle-aged (10 5 -10 7 yr), nearby (d0.13-2 kpc) neutron stars with no strong radio emission. Their proximity
to the Sun makes them diфcult to identify in traditional large-scale surveys for radio pulsations because they have
eectively zero dispersion, making them hard to distinguish from terrestrial interference. We propose a very deep
targeted search for radio pulsations from two northern isolated neutron stars at 430 ~
MHz. A detection would allow
subsequent timing to determine their ages. A non-detection can be used to help constrain the fraction of
radio-quiet neutron stars.

I might want to do remote observing.
Instrument Setup
430 CH receiver L-narrow
Atmospheric Optical Instruments:
Special Equipment or setup: I will use the PSPM. The L-narrow feed will be
used only in the case of bad RFI at 430 MHz.
RFI Considerations
Frequency Ranges Planned
425 - 435
This proposal requires coordination with AFTWF within the band 425-435 MHz.
