Polarimetric Observations of a New Circumstellar Disk System

چکیده
Few circumstellar disks have been directly observed. Here we use sensitive differential polarimetric techniques to overcome atmospheric speckle noise in order to image the circumstellar material around HD 169142. The detected envelope or disk is considerably smaller than expectations based on the measured strength of the far-IR excess from this system.

Imaging Polarimetric Observations of a New Circumstellar Disk System
Few circumstellar disks have been observed directly. Here we use sensitive differential polarimetric techniques to overcome atmospheric speckle noise in order to image the circumstellar material around HD 169142. The detected envelope or disk is considerably smaller than expectations based on the measured strength of the farIR excess from this system. Subject headings: circumstellar matter — te...
متن کاملMagnetic Accretion and Photopolarimetric Variability in Classical T Tauri Stars
We employ a Monte Carlo radiation transfer code to investigate the multiwavelength photopolarimetric variability arising from a spotted T Tauri star surrounded by a dusty circumstellar disk. Our aim is to assess the ability of the magnetic accretion model to explain the observed photopolarimetric variability of classical T Tauri stars, and to identify potentially useful observational diagnostic...
متن کاملNACO Polarimetric Differential Imaging of TW Hya : A Sharp Look at the Closest T Tauri Disk ⋆
We present high-contrast imaging data on the disk of the classical T Tauri star TW Hya. The images were obtained through the polarimetric differential imaging technique with the adaptive optics system NACO. Our commissioning data show the presence of polarized disk emission between 0.1 ′′ and 1.4 ′′ from the star. We derive the first Ks-band radial polarized intensity distribution. We show that...
متن کاملOn the Determination of the Rotational Oblateness of Achernar
The recent interferometric study of Achernar, leading to the conclusion that its geometrical oblateness cannot be explained in the Roche approximation, has stirred substantial interest in the community, in view of its potential impact in many fields of stellar astrophysics. It is the purpose of this paper to reinterpret the interferometric observations with a fast rotating, gravity darkened cen...
متن کاملar X iv : a st ro - p h / 01 06 51 7 v 1 2 8 Ju n 20 01 A close view on the protoplanetary disk in the Bok globule CB 26
We present new sub-arcsecond-resolution near-infrared polarimetric imaging and millimetre interferometry data on the circumstellar disk system in the Bok globule CB26. The data imply the presence of a M ≥ 0.01 M⊙ edge-on-seen disk of > 400 AU in diameter, being in Keplerian rotation around a young ∼0.35 M⊙ star. The mm dust emission from the inner 200 AU is highly optically thick, but the outer...
