Discovery of an Optically Thick , Edge - on Disk around the Herbig Ae star PDS 144
We have discovered an optically thick, edge-on circumstellar disk around a Herbig Ae star in the binary system PDS 144, providing the first intermediatemass analog of HK Tau and similar T Tauris. This system consists of a V ∼ 13 mag. primary and a fainter companion, with spectra of both stars showing evidence for circumstellar disks and accretion; both stars were classified as Herbig Aes by the...
متن کاملOn the difference between Herbig Ae and Herbig Be stars
We present linear spectropolarimetric data for eight Herbig Be and four Herbig Ae stars at Hα, Hβ and Hγ. Changes in the linear polarisation are detected across all Balmer lines for a large fraction of the observed objects, confirming that the smallscale regions surrounding these objects are flattened (i.e. disk-like). Furthermore, all objects with detections show similar characteristics at the...
متن کاملThe Herbig Ae SB2 system HD 104237
We present here the most recent abundance analysis of this Herbig Ae system based on high-resolution UVES and HARPS spectra and the results of our magnetic field measurements using high-resolution spectra obtained with HARPSpol.
متن کاملBinaries among Herbig Ae/Be stars
We have studied the circumstellar environment of 31 Herbig Ae/Be and related stars in the near infrared by means of speckle-interferometry. For the brighter objects we reach or approximate diffraction-limited resolution of ≈ 0.1′′ (typically 100 AU at the object). Of the resolved objects some show halos, some have a companion. Here we restrict ourselves to a discussion of binarity in this sampl...
متن کاملAccretion Rates in Herbig Ae stars
Accretion rates from disks around pre-main sequence stars are of importance for our understanding of planetary formation and disk evolution. We provide in this paper estimates of the mass accretion rates in the disks around a large sample of Herbig Ae stars. We obtained medium resolution 2 μm spectra and used the results to compute values of Ṁacc from the measured luminosity of the Brγ emission...
