In the high resolution optical spectra we identified forbidden lines of [OI] and [CI], which indicate the presence of low excitation nebula. There are many...

HD 331319 is a F3 Ib star with a detached cold circumstellar dust shell with far-IR colours similar to planetary nebulae. From an analysis of high resolution...

IRAS 10215-5916 was classified as a post-AGB star and also as a massive red supergiant. It was also found to be a spectroscopic binary. In our high resolution...

We have carried out an analysis of the high resolution optical spectra of post-AGB candidates SAO 85766 (IRAS 18062+2410), SAO 34504 (IRAS 22272+5435), HD...

Samples of line-of-sight velocities and metallicities for hundreds individual red giant branch stars in Milky Way satellite galaxies have been obtained in the...

Since the discovery of the first planet outside the solar system, the number of planet detections is increasing exponentially. Although we have not been capable...

Through ground-based observations of the Earth's spectrum from California, satellite observations of clouds, and an atmospheric radiative transfer code, we have...

We present preliminary results of long-slit spectroscopic observations of the extended emission line region (hereafter, EELR) in NGC 4388. We detect broad...
