A representative sample of Be stars III: H band spectroscopy
We present H band (1.53 μm–1.69 μm) spectra of 57 isolated Be stars of spectral types O9-B9 and luminosity classes III, IV & V. The H i Brackett (n–4) series is seen in emission from Br-11–18, and Fe ii emission is also apparent for a subset of those stars with H i emission. No emission from species with a higher excitation temperature, such as He ii or C iii is seen, and no forbidden line emis...
متن کاملSubmillimeter lines from circumstellar disks around pre-main sequence stars
Observations of submillimeter lines of CO, HCO, HCN and their isotopes from circumstellar disks around low mass pre-main sequence stars are presented. CO lines up to J=6→5, and HCO and HCN lines up to J=4→3, are detected from the disks around LkCa 15 and TW Hya. These lines originate from levels with higher excitation temperatures and critical densities than studied before. Combined with interf...
متن کاملLine emission from circumstellar disks around A stars
The nature of the tenuous disks around A stars has raised considerable controversy in the literature during the past decade. The debate whether or not the disk around β Pictoris contains gaseous molecular hydrogen is only the most recent example. Since CO is in general a poor tracer for the gas content of these low mass disks, we discuss here detailed emission line calculations for alternative ...
متن کاملFlash Spectroscopy: Emission Lines from the Ionized Circumstellar Material around < 10-day-old Type Ii Supernovae
Supernovae (SNe) embedded in dense circumstellar material (CSM) may show prominent emission lines in their early-time spectra (≤ 10 days after the explosion), owing to recombination of the CSM ionized by the shock-breakout flash. From such spectra (“flash spectroscopy”), we can measure various physical properties of the CSM, as well as the mass-loss rate of the progenitor during the year prior ...
متن کاملForbidden emission lines in Herbig Ae/Be stars
The absence of high velocity redshifted forbidden lines in classical T-Tauri stars (Appenzeller et al. 1984; Edwards et al. 1987) has long be taken as evidence of opaque circumstellar disks: disks which occlude the receding component of the stellar wind or outflow, allowing only the blueshifted emission to be observed. There has been some controversy in the literature recently as to whether a d...
