Supernova 1993J - A veiled pulsar in a binary system?
The recent report of a binary companion to the progenitor of supernova 1993J may provide important clues for identifying the nature of the nascent compact object. Given the estimates of the progenitor mass, the potential power source is probably a pulsar rather than an accreting black hole. If there is a pulsar, one would expect the rotational luminosity to be stored and reprocessed by the supe...
متن کاملModelling the binary progenitor of supernova 1993J
We have developed a detailed stellar evolution code capable of following the simultaneous evolution of both stars in a binary system, together with their orbital properties. To demonstrate the capabilities of the code we investigate potential progenitors for the Type IIb supernova 1993J, which is believed to have been an interacting binary system prior to its primary exploding. We use our detai...
متن کاملSupernova 2008d: a Repetition of Supernova 1987a in a Binary
The Supernova 2008D is similar to that of SN 1987Awithout the H-envelope. Soderberg et al. (2008) reported the serendipitous discovery of the SN2008D at the time of the explosion, accompanied by an X-ray outburst XRF080109. The central remnant, which we believe to be the black-hole (BH) central engine in the Blandford-Znajek mechanism, is estimated, on the basis of the 7% Ni production, to have...
متن کاملPulsar/Supernova Remnant Associations
Pulsar/Supernova Remnant Associations Vicky Kaspi Infrared Processing & Analysis Center, Jet Propulsion Laboratory/ California Institute of Technology Since the discovery of the first pulsar/supernova remnant association not long after the discover of pulsars themselves, the number of proposed associations has grown to nearly 20. In this talk we will critically review the known and proposed sup...
متن کاملPsr J1518+4904: a Mildly Relativistic Binary Pulsar System
PSR J1518+4904 is a recently discovered 40.9 ms pulsar in an 8.6 day, moderately eccentric orbit. We have measured pulse arrival times for this pulsar over 1.4 yr at several radio frequencies, from which we have derived high precision rotational, astrometric, and orbital parameters. The upper limit for the period derivative of the pulsar, Ṗ < 4 × 10, gives a characteristic age of at least 1.6 ×...
