H{alpha} emission-line objects in SMC clusters
Slitless CCD spectra were obtained covering the bulk (about 3 square degrees) of the Small Magellanic Cloud. For H{alpha} line-emission twice as strong as the ambient continuum,... -
Spectroscopic analysis of RJHA 49 and SS73 21
We investigate the spectra and the evolutionary stages of two peculiar emission-line stars: RJHA 49 and SS73 21. We used low and high resolution optical data. Line... -
Bright Be shell stars
Echelle observations are presented and discussed for 23 of the 27 known "normal" shell stars brighter than about 6.5mag. In addition to those typical cases, three stars with... -
UBV photometry of HD 6226
Photometric and spectroscopic monitoring of the B star resulted in the finding that this object is a new bright Be star with a clear positive correlation between the brightness... -
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... -
Atlas of B6-A2 hyper- and supergiants
We present an atlas of spectra of 5 emission-line stars: the low-luminosity luminous blue variables (LBVs) HD 168625 and HD 160529, the white hypergiants (and LBV candidates) HD... -
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This paper presents a catalogue of previously unpublished optical and infrared photometry for a sample of 162 emission-line objects and shell stars visible from the southern... -
H-alpha Stars in Northern Milky Way
The catalogue contains 4174 stars in the Northern Milky Way, in the range 32{deg}<l<214{deg}, -10{deg}<b<+10{deg}, having the H line in emission. The HBH list (main... -

Allsky cross-matched 3XMMe catalogue
ARCHES (Astronomical Resource Cross-matching for High Energy Studies) is a FP7-Space funded project whose aim is to provide the astronomical community with well-characterised... -
Gaia-IPHAS/KIS Value-Added Catalogues
We present a sub-arcsecond cross-match of Gaia DR2 (Cat. I/345) against the INT Photometric H-alpha Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2, Cat. II/321)... -
Vatican Emission-line stars
The survey represents a search for H{alpha} emission-line stars, and was conducted with a 12{deg} objective prism on the Vatican Schmidt telescope. The Vatican Emission Stars... -
Stars with CaII H and K emission
Intensities and widths of emission cores of H and K lines from the literature are presented for over 1400 stars of spectral types F, G, K and M. Cone search capability for table... -
IPHAS DR2 Source Catalogue
The INT/WFC Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS) is a 1860 deg^2^ imaging survey of the Northern Milky Way at red visible wavelengths. It covers... -
H{alpha} emission stars in the Orion Nebula
The catalog of 534 H{alpha} emission lines stars in the region of the Orion Nebula (5{deg}x5{deg}) is presented, an the basis of 240 "new" H{alpha} stars found on Tonantzintla... -
Optical spectroscopy of classical Be stars
In this study, we analyse the emission lines of different species present in 118 Galactic field classical Be stars in the wavelength range of 3800-9000{AA}. We re-estimated the... -
SMC emission-line objects
H{alpha} and [OIII] narrow-band, wide-field (7x7deg^2^), CCD images of the Small Magellanic Cloud were compared, and a catalogue of candidate planetary nebulae and H{alpha}... -
128 new Herbig stars
We present optical spectroscopy observations of 145 high-mass pre-main-sequence candidates from the catalog of Vioque et al. (2020, PhD thesis University of Leeds) From these,...
