Is the Bursting Radio-source Gcrt J1745-3009 a Double Neutron Star Binary ?
GCRT J1745-3009 is a peculiar transient radio-source in the direction of the Galactic Center. It was observed to emit a series of ∼ 1 Jy bursts at 0.33 GHz, with typical duration ∼ 10 min and at apparently regular intervals of ∼ 77 min. If the source is indeed at the distance of the Galactic Center as it seems likely, we show that its observational properties are compatible with those expected ...
متن کاملGCRT J1745-3009: A precessing radio pulsar?
A unique transient bursting radio source, GCRT J1745-3009, has been discovered (Hyman et al. 2005a) near the direction of the Galactic center. It is still an open question to explain this phenomenon, although some efforts to understand its nature have been made. This paper shows that most of the observed features can be reproduced by our proposed precessing pulsar model. It is found that the pr...
متن کاملGcrt J1745-3009: a Freely Precessing Pulsar?
A bursting radio source, GCRT J1745-3009, had been discovered by Hyman et al. (2005) near the direction of the Galaxy center. It bursts with a period of ∼ 77 min and a duration of ∼ 10 min. The source is very luminous during its burst state, which implies that it is not an incoherent emitter. It is still open to explain this phenomenon although a couple of scenarios had been proposed by Hyman e...
متن کاملGcrt J1745-3009 as a Transient White Dwarf Pulsar
A transient radio source in the direction of the Galactic Center, GCRT J1745-3009, exhibited 5 peculiar consecutive outbursts at 0.33 GHz with a period of 77.13 minutes and a duration of ∼ 10 minutes for each outburst. It has been claimed to be the prototype of a hitherto unknown class of transient radio sources. We interpret it as a transient white dwarf pulsar with a period of 77.13 minutes. ...

GCRT J1745−3009 is a transient bursting radio source located in the direction of the Galactic center. It was discovered in a 330 MHz VLA observation from 2002 September 30–October 1 and subsequently rediscovered in a 330 MHz GMRT observation from 2003 September 28 by Hyman et al. Here we report a new radio detection of the source in 330 MHz GMRT data taken on 2004 March 20. The observed propert...
