Is the X-ray pulsar H 0253 + 193 a neutron star spun down in a molecular cloud?

Abstract

The detection of 206s X-ray pulsations from H0253+193 indicates that the source is a compact object. It is argued here that object can not be a T Tauri star or Be/X –ray binary pulsar suggested that H 0253+193 is slowly rotating single neutron star now accreting interstellar matter after having been spun down by a propeller type mechanism during its passage through cloud.
