DETECTION OF BETA-PICTORIS-LIKE GASEOUS INFALL IN 2-ANDROMEDAE

Ultraviolet observations of 2 Andromedae with the Goddard High Resolut ion Spectrograph on board the Hubble Space Telescope (HST) clearly rev eal the existence of circumstellar gas, in addition to previously know n anomalous interstellar features, in the line of sight toward this ne arby star. We also detect varying, redshifted Ca II absorptions, which we interpret as gaseous infalls. These variable Ca II absorption feat ures and the presence of circumstellar absorptions from Al III lambda lambda 1854.716 and 1862.790 and from excited fine-structure levels of Fe II near 2600 Angstrom seen in 2 And are similar to those observed in spectra of beta Pic.
