| 内容記述 | A spectrum of the star Spica (Alpha Virginis) from 960 to 1270 A was recorded by a rocket-borne spectrograph March 13, 1988. The spectrum, which has 3.4 A resolution, shows a much sharper drop-off in intensity near 1050 A than similar measurements made by the Voyager UVS, but is in good agreement with the spectrum obtained by Brune et al. in a 1977 sounding rocket. The disagreement with Voyager is a factor of 1.5 at 1100 A and grows to a factor of 5.7 at 960 A. This implies that the photometric standards between 912 and 1100 A may need some revision, and that the standard photospheric models for hot stars may err significantly near the Lyman limit. |
