Abstract

New results of optical observations of isolated pulsars and their environments are presented. Very Large Telescopes observations of PSR J0108-1431 set an upper limit of B ∼ 28.6 on its optical flux, implying a neutron star surface temperature T < 8.8 × 10 4 K (for d = 200 pc, R = 13 km). HST proper motion measurement of the PSR 1929+10 counterpart secured its optical identification. Finally, deep observations of the Vela pulsar field did not confirm the presence of an optical pulsar wind nebula (PWN).
