A Massive Planet to the Young Disc Star HD 81040 ⋆
We report the discovery of a massive planetary companion orbiting the young disc star HD 81040. Based on five years of precise radial-velocity measurements with the HIRES and ELODIE spectrographs, we derive a spectroscopic orbit with a period P = 1001.0 days and eccentricity e = 0.53. The inferred minimum mass for the companion of m 2 sin i = 6.86 M Jup places it in the high-mass tail of the ex...
متن کاملA 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 کاملDisks around Young O-B (Proto)Stars: Observations and Theory
Disks are a natural outcome of the star formation process in which they play a crucial role. Luminous, massive stars of spectral type earlier than B4 are likely to be those that benefit most from the existence of accretion disks, which may significantly reduce the effect of radiation pressure on the accreting material. The scope of the present contribution is to review the current knowledge abo...
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 ...
