چکیده

The results of multicolor photometric and lowresolution spectroscopic observations of 9 Herbig Ae/Be candidate stars are reported. This sample includes two newly recognized objects, MQ Cas and BD+11829, which were found by means of cross-correlation of the IRAS Point Source Catalogue and the catalogue of the galactic early-type emission-line stars (Wackerling 1970). Near-IR excesses were detected in two stars (AS 116 and BD+11829) for the first time. Algol-type variability, which is not common in Herbig Ae/Be stars, was detected in MQ Cas and V1012 Ori. Spectral types are determined for MQ Cas, GSC 1811−0767, HDE 244604, BD+11829, V1012 Ori, AS116, AS117, and HDE 290380 from low-resolution spectroscopy. Analysis of our and previously published data suggests that 8 of the 9 objects are pre-main-sequence stars, while the last one, Hen 938, is more likely a B[e] supergiant.

Magnetic fields of Herbig Ae/Be stars

We report on the status of our spectropolarimetric studies of Herbig Ae/Be stars carried out during the last years. The magnetic field geometries of these stars, investigated with spectropolarimetric time series, can likely be described by centred dipoles with polar magnetic field strengths of several hundred Gauss. A number of Herbig Ae/Be stars with detected magnetic fields have recently been...

Probing the circumstellar structure of Herbig Ae/Be stars

We present Hα spectropolarimetry observations of a sample of 23 Herbig Ae/Be stars. A change in the linear polarisation across Hα is detected in a large fraction of the objects, which indicates that the regions around Herbig stars are flattened (disclike) on small scales. A second outcome of our study is that the spectropolarimetric signatures for the Ae stars differ from those of the Herbig Be...

Wind diagnostics and correlations with the near-infrared excess in Herbig Ae/Be stars

Intermediate dispersion spectroscopic observations of 37 Herbig Ae/Be stars reveal that the equivalent widths of their [OI]λ6300 andHα emission lines, are related to their nearinfrared colours in the same fashion as the T-Tauri stars. Such a correlation strongly supports the idea that the winds from Herbig Ae/Be stars arise in the same manner as those from TTauri stars, i.e. through accretion d...

An ultraviolet, optical and infrared study of Herbig Ae/Be stars

We have selected a list of 45 Herbig Ae/Be-type candidates on the base of their IRAS colors and their spectral types. We propose the presence of a broad infrared excess as a defining criterion for these stars, rather than the detection of circumstellar nebulosity. In this way, our selection also includesmore evolved young stars, that are no longer embedded in their star-forming region. A few ob...

Near-Infrared Photometric Survey of Herbig Ae/Be Candidate Stars

We report near-infrared photometric measurements of 35 Herbig Ae/Be candidate stars obtained with direct imaging and aperture photometry. Observations were made through the broadband J , H , and K ′ filters, with each source imaged in at least one of the wavebands. We achieved subarcsecond angular resolution for all observations, providing us with the opportunity to search for close binary cand...
