J1709-1640 belongs to small class of pulsars which null on intermediate timescales (~hour). Such pulsars represent important link between the classical nullers (whose emission vanishes few rotations and the intermittent pulsars which null for months and years. We have observed this pulsar for ~50 hours using Ooty Radio Telescope (ORT). Unlike its counterparts whose inactive states are fairly regular, this pulsar goes into inactive state very rarely ( ~ 5 days ). This makes a unique addition to the sample of intermediate nullers. A part from occasional inactive states this pulsar has regular nulls. We have identified and characterized the nulling behaviour of this pulsar. We will present these results. |
