HD 100453 AB system ALMA images
The complex system HD 100453 AB with a ring-like circumprimary disk and two spiral arms, one of which is pointing to the secondary, is a good laboratory in which to test spiral... -
MWC 480 ALMA image
Gap-like structures in protoplanetary disks are likely related to planet formation processes. In this work, we present and analyze high-resolution 1.3mm ALMA continuum... -
A search for accreting young companions
In recent years, our understanding of giant planet formation progressed substantially. There have even been detections of a few young protoplanet candidates still embedded in... -
Space photometry of the Be stars nu Pup
Photometry of the bright Be star {nu} Puppis. The observations were obtained with the Solar Mass Ejection Imager (SMEI) and BRITE-Constellation satellites. Several closely but... -
Gaia DR2 study of Herbig Ae/Be stars
We use Gaia Data Release 2 (DR2, Cat. I/345) to place 252 Herbig Ae/Be stars in the HR diagram and investigate their characteristics and properties. For all known Herbig Ae/Be... -
IR nebulae around bright massive stars
Recent studies show that more than 70% of massive stars do not evolve as effectively single stars, but as members of interacting binary systems. The evolution of these stars is... -
Identifying gaps in flaring Herbig Ae/Be disks
The evolution of protoplanetary disks towards mature planetary systems is expected to include the formation of 'gaps' in the disk possibly due to planet formation. We studied... -
MHO Catalogue
We present a catalogue of Molecular Hydrogen emission-line Objects (MHOs) in outflows from young stars, most of which are deeply embedded. All objects are identified in the... -
Disk of {upsilon} Sgr
The aim of this paper is to determine the properties of the dusty environment of the hydrogen-deficient binary system upsilon Sgr, whose binary properties and other... -
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...
