A Disk Wind Driving the Rotating Molecular Outflow in CB 26

چکیده
We present 12CO (J=2-1) sensitive molecular line and 1.3 mm continuum observations made with the Submillimeter Array (SMA) of bipolar outflow associated young star located in Bok globule known as CB 26. The SMA were carried out its extended configuration allowing us to study kinematics structure about 1 arcsec or 140 au resolution. find that dusty edge-on circumstellar disk related has an projected spatial (deconvolved) size 196 x 42 a total (gas dust) mass 0.031 Msun. estimated dynamical for central object 0.66 Msun, 5x10-5 confirm rotation similar orientation disk. For outflow, we following quantities: velocity, specific angular momentum, launching radius, decrease height above mid-plane, observed other rotating outflows. expansion velocity also increase midplane. Estimations linear momentum rate, accretion luminosity seem be well explained by wind CB26.

Rotating molecular outflows : the young T Tauri star in CB 26 ⋆
Context. The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming proto-star. Though jet rotation has been observed in a few objects, no rotation of molecular outflows has been unambiguously reported so far. Aims. We report new millimeter-interferometric observations of the edge-on T Tauri star – disk system in the isolated Bok globule CB 26...
متن کاملHigh - resolution NIR Observations of the Circumstellar Disk System in the Bok Globule CB 26 1
We report on results of near-infrared and optical observations of the mm disk embedded in the Bok globule CB 26 (Launhardt & Sargent 2001). The near-infrared images show a bipolar reflection nebula with a central extinction lane which coincides with the mm disk. Imaging polarimetry of this object yielded a polarization pattern which is typical for a young stellar object surrounded by a large ci...
متن کاملA molecular disk and dense outflow in Corona Australis
The central region of the molecular outflow in the R Coronae Australis cloud was mapped in HCO+(J = 1 − 0), H13CO+(J = 1 − 0), HCO+(J = 3 − 2) and C18O(J = 2 − 1) with the SEST. In addition to the maps, selected positions were observed in SiO(J = 2 − 1, v = 0). The observations reveal a complex system consisting of a dense core, a rotating molecular disk around the infrared source IRS 7 and a d...
متن کاملBoundary Layers and Heat Transfer on a Rotating Rough Disk
The study of flow and heat transfer over rotating circular disks is of great practical importance in understanding the cooling of rotatory machinery such as turbines, electric motors and design and manufacturing of computer disk drives. This paper presents an analysis of the flow and heat transfer over a heated infinite permeable rough disk. Boundary-layer approximation reduces the elliptic Nav...
متن کاملThe circumstellar disc in the Bok globule CB 26
Context. Circumstellar discs are expected to be the nursery of planets. Grain growth within such discs is the first step in the planet formation process. The Bok globule CB 26 harbours such a young disc. Aims. We present a detailed model of the edge-on circumstellar disc and its envelope in the Bok globule CB 26. Methods. The model is based on HST near-infrared maps in the I, J, H, and K bands,...
