The Abundances of the Noble Gases Neon and Xenon in the Atmosphere of 53 Tau (HD 27295).

MONIER R.

Abstract (from CDS):

One line of Ne I and three lines of Xe II are synthesized in order to derive the abundances of neon and xenon in the atmosphere of the Mn-rich star 53 Tau. Neon is clearly very underabundant in 53 Tau, its abundance must be lower than 10–3 times the solar neon abundance. Xenon is found to be overabundant with a factor of 3000 times the solar abundance which agrees well with earlier measurements. The underabundance of neon is expected from radiative acceleration calculations which show that neon has a very small radiative acceleration in the photosphere.

within 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!). sed-help-icon
