The gamma-ray source LSI +61deg303. II. Multiwavelength emission model.

LEAHY D.A.

Abstract (from CDS):

The multi-wavelength spectrum of LSI +61°303 is summarized. The X-ray to γ-ray luminosity of Lic≃1.5x1035erg/s is due to inverse Compton emission from relativistic electrons around a pulsar. The X-ray to γ-ray spectrum determines the electron energy index, which is consistent with the observed radio spectrum if it mainly optically thin. The inverse Compton emission from a compact region of electrons peaks at periastron due to the higher density of stellar photons. This compact region is highly self-absorbed at radio frequencies implying the quiescent radio emission comes from a separate diffuse population of electrons. The number and total energy of electrons in the diffuse region is ∼0.1 of that in the compact region (∼3x1043 electrons, ∼5x1038erg). The compact region cannot be static due to its high internal pressure: expansion leading to loss of electrons and injection of new electrons are required. A pulsar with spin period ≃0.1s can provide sufficient injection power. A steady diffuse outflow of electrons from the compact region produces too much optically thick synchrotron emission. The alternative is bulk expansion of the compact electron bubble, with dynamic pressure limiting the expansion velocity and resulting in expansion away from the Be star. Injection ends as the bubble wall facing the Be star stalls and the pulsar's orbit takes it out of the bubble. Alternately, the Rayleigh-Taylor instability could cause the bubble to break up before the exit of the pulsar. In either case, energy injection rates of ∼2 Lic into the bubble result in a detached bubble of size, velocity and electron content similar to the initial conditions used by Peracaula (1997, Ph.D. Thesis, University of Barcelona) to model radio outbursts for LSI +61°303.

within radius arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
