Scientific paper

Constraints on the configuration of the presupernova progenitor of the binary pulsar system are examined, using limits on the proper motion of PSR 1913 + 16. The sensitivity of pulse shape data to geodetic precession of the pulsar spin axis is studied in an effort to limit explosion asymmetries perpendicular to the orbital plane of the progenitor. It is found that all alignment of spin axis and orbital angular momentum is not yet demanded by observations. Observations which should narrow the allowed range of presupernova masses and radii are discussed.
