UVBRI photometry and spectroscopy of AG Dra
Photometric UBVri observations of the symbiotic star AG Dra in Piwnice Observatory, Torun, Poland, are presented in tables 2 and 3. The 60cm telescope and a single-channel... -
Stephenson H{alpha} stars
We present the results of spectroscopic observations for 52 objects from the list of H{alpha} emission stars of Stephenson (1986ApJ...300..779S). Out of six known T Tauri stars... -
UBV photometry of V832 Cyg
An analysis of numerous homogenized UBV photoelectric observations and red spectra of the Be star from several observatories is presented. -
Southern emission-line stars multiphotometry
This paper presents a catalogue of previously unpublished optical and infrared photometry for a sample of 162 emission-line objects and shell stars visible from the southern... -
BV(RI)c photometry of 7 symbiotic stars
File table1.dat contains the UBV(RI)c magnitudes of the symbiotic stars AS 323, Ap 3-1, CM Aql, V1413 Aql, V443 Her, V627 Cas, V919 Sgr estimated on the Asiago archive plates.... -
H{alpha} emission objects in the southern Milky Way
The stars reported in James Wray's PhD thesis result from photographic plates taken by Karl Henize in South Africa during 1949-1951 covering the Southern Galactic plane to about... -
Preliminary Catalog Early-Type Emission Stars
The present catalogue presents a list of 3216 stars mostly earlier than type F which have shown emission features and specifically one or more lines of the Balmer series in... -
SS(77) Catalogue: new H-alpha em* in Milky Way
Data on 455 H-{alpha} emission stars found in all parts of the Milky Way, virtually all previously unpublished, are tabulated, with newly measured coordinates usually accurate... -
Early-Type Emission-Line Stars
The catalog contains 5326 early-type emission-line stars. Of these, 1424 have no spectral classification but are assumed to be of early type. Some 71 percent of the stars listed... -
H-alpha emission stars in the Orion region
Extensive survey observations were carried out for H-alpha emission stars in six Kiso Areas in the Orion region. The observations were made using mainly the Kiso Schmidt... -
Ha emission-line stars & Herbig Ae/Be from LAMOST
We derive a catalog of early-type emission-line stars including 30023 spectra of 25867 stars from LAMOST Data Release 7, in which 4189 have Simbad records. The spectra are... -
byH{alpha} photometry in open clusters
Be stars are a class of rapidly rotating B stars with circumstellar disks that cause Balmer and other line emission. There are three possible reasons for the rapid rotation of...
