... Photosphere of the Unique DO = White Dwarf RE/J0503-289) The High Resolution Spectrograph (Side Two) was used to make = spectrographic observations of the unique DO Class, helium rich, white = dwarf star REJ0503-28 in order to study its stellar winds and ...
... The SEDs of oxygen- and carbon-rich AGB stars are compared with appropriate stellar photosphere models to obtain the excess flux in all the IRAC bands and the MIPS 24 ЮМm band. ...
... The lower left panel shows two ISO spectra of Wolf-Rayet stars, one with no dust where the photosphere and the typical broad Wolf-Rayet emission lines are seen and one with a lot of dust which shows a relatively featureless continuum and a broad ...
... I further discuss how the models, together with HST/STIS spectral observations, have led to a fundamental rethinking of how the binary companion affects the extended optically-thick wind photosphere of the LBV primary. ...
... 1.2 Completed Two Sets of STIS/CCD/MA1 8149 (The Spectral Energy Distribution of a Neutron Star Photosphere) The Space Telescope Imaging Spectrograph (CCD and MA1) was used to make direct measurement of the radius or mass of any neutron star outside a ...
... Such an optically thin component might be associated with the transition region ("chromosphere") between the disk photosphere and the fast wind from the system, whose presence has been suggested by Knigge Drew (1997). ...

... the presence of a high column ($N_H \sim10^{23}$~cm$^{-2}$), relatively dense ($n_e \simeq 4 \times 10^{12}$~cm$^{-3}$) and only slowly-outflowing ($v_{poloidal} \ll v_{escape}$) transition region between the disk photosphere and the fast-moving wind ...
