A Keplerian disk around the Herbig Ae star HD 34282
We report new millimeter observations of the circumstellar material surrounding the Herbig Ae A0.5 star HD 34282 performed with the IRAM array in CO J = 2 → 1 and in continuum at 1.3 mm. These observations have revealed the existence of a large Keplerian disk around the star. We have analysed simultaneously the line and continuum emissions to derive the physical properties of both the gas and t...
متن کاملA Keplerian Disk around the Herbig Ae star HD 169142
We present Submillimeter Array observations of the Herbig Ae star HD169142 in 1.3 millimeter continuum emission and 12 CO J=2-1 line emission at ∼ 1. ′′ 5 resolution that reveal a circumstellar disk. The continuum emission is centered on the star position and resolved, and provides a mass estimate of ∼ 0.02 M ⊙ for the disk. The CO images show patterns in position and velocity that are well mat...
متن کاملA Keplerian Gaseous Disk around the B 0 Star R Mon
We present high-angular resolution observations of the circumstellar disk around the massive Herbig Be star R Mon (M * ∼8 M ⊙) in the continuum at 2.7mm and 1.3mm and the 12 CO 1→0 and 2→1 rotational lines. Based on the new 1.3mm continuum image we estimate a disk mass (gas+dust) of 0.007 M ⊙ and an outer radius of <150 AU. Our CO images are consistent with the existence of a Keplerian rotating...
متن کاملDisk Surrounding the Massive Main Sequence Star Mwc 297 ?
We present the results of the interferometric observations of the circumstellar disk surrounding MWC 297 in the continuum at 230 GHz (1.3 mm) and in the (J=2-1) rotational transitions of 12CO,13CO and C18O using the Submillimeter Array. At a distance of 250 pc, MWC 297 is one of the closest, young massive stars (M⋆ ∼10 M⊙) to us. Compact continuum emission is detected towards MWC 297 from which...
متن کاملAnatomy of a flaring proto-planetary disk around a young intermediate-mass star.
Although planets are being discovered around stars more massive than the Sun, information about the proto-planetary disks where such planets have built up is sparse. We have imaged mid-infrared emission from polycyclic aromatic hydrocarbons at the surface of the disk surrounding the young intermediate-mass star HD 97048 and characterized the disk. The disk is in an early stage of evolution, as ...
