Optical and near-IR observations of variable stars with AURELIE.

VIOTTI R., ROSSI C. and MURATORIO G.

Abstract (from CDS):

We report high and intermediate resolution spectroscopic observations of many emission line stars mainly observed with Aurelie at the 1.52 m OHP telescope in December 1990 and January 1995, with special attention to the Hα and 1µm regions. The near-IR observations of the Be star γ Cas disclosed the presence of a very strong fluorescence Fe II 1.00µm emission, with intensity and profile similar to that of Pδ. Both have varied between 1990 and 1995. The Fe II 1.00µm line is also weakly present in emission in β Ori, and in the 1990 and 1995 spectra of the VV Cep star KQ Pup. The high resolution 1995 observations of the yellow hypergiant HR 8752 disclosed a broad [N II] emission, and Hα with multiple components. The slow approaching of the KQ Pup system to periastron is marked by the large strengthening of the Hα emission between 1984 and 1995. Strong variation in Hα intensity was also found in the yellow symbiotic star AG Dra observed in quiescence and during its recent active phase. The red symbiotic star CH Cyg was especially interesting for the large profile variation of the Balmer lines on a daily time scale in January 1995. We detected expansion velocities of up to 2000km/s. In December 1990 the yellow spectrum of CH Cyg displayed a broad He I 587nm absorption, which turned to strong emission in 1995. We also report observations of π Aqr, R Aqr, EZ CMa, β CMi, and HD 200775.
