The Astrophysics of Emission-Line Stars [PDF]
Astrophysics and Space Science Library, 2007 Many types of stars show conspicuous emission lines in their optical spectra. These stars are broadly referred to as emission line stars. Emission line stars are attractive to many people because of their spectacular phenomena and their variability.

Journal of Mathematical and Fundamental Sciences, 2019 Hα line variations of 8 B-emission (Be) stars are presented. Stars that are listed in the Bright Star Catalogue were observed in 2009 at the Bosscha Observatory, Lembang, Indonesia. It was found that 4 stars showed phase changing from Be double-peaked to

Emission-line Stars and Early-type Stars with Gaia
EAS Publications Series, 2010 Gaia will provide accurate parallaxes, spectrophotometry and spectroscopy for hundreds of thousands of emission-line stars across the whole HR diagram. In preparation for the Gaia mission, we are developing algorithms to recognize and classify emission ...

Symbiotic stars and other Hα emission-line stars towards the Galactic bulge★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 Symbiotic stars are interacting binaries with the longest orbital periods and their multi-component structure makes them rich astrophysical laboratories. The accretion of a high mass loss rate red giant wind on to a white dwarf (WD) makes them promising Type Ia supernovae (SNe Ia) progenitors.

Line emission from circumstellar disks around A stars [PDF]
, 2003 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 beta Pictoris contains gaseous molecular hydrogen is only the most recent example ...

A Study of Emission Lines in Carbon Stars
The Astrophysical JournalCarbon stars are chemically peculiar stars with high carbon abundance, showing strong carbon molecule bands and rare emission lines in their spectra. This paper explores the stellar activity of carbon stars by identifying emission line features in their ...
