Extreme ultraviolet explorerobservations of psr b0656+14
(IOP Publishing, 2000-08-20)The pulsar PSR B0656 + 14 has been observed at gamma-ray, X-ray, EUV, and optical energies. These data are consistent with emission originating from a thermal stellar surface augmented by a hot, thermal "polar-cap" ... -
Rotational modulation of the radio emission from the m9 dwarf tvlm 513−46546: broadband coherent emission at the substellar boundary?
(IOP Publishing, 2006-12-10)The Very Large Array was used to observe the ultracool rapidly rotating M9 dwarf TVLM 513-46546 simultaneously at 4.88 and 8.44 GHz. The radio emission was determined to be persistent, variable, and periodic at both ... -
The creation of the helix planetary nebula (ngc 7293) by multiple events
(Oxford University Press (OUP), 2005-07-01)A deep continuum-subtracted image of NGC 7293 has been obtained in the light of the H alpha+[N II] emission lines. New images of two filamentary halo structures have been obtained, and a possible detection of a collimated ...
