Low - mass star formation in Lynds 1333
Medium-resolution optical spectroscopy of the candidate YSOs associated with the small, nearby molecular cloud Lynds 1333 revealed four previously unknown classical T Tauri stars, two of which are components of a visual double, and a Class I source, IRAS 02086+7600. The spectroscopic data, together with new V,RC , IC photometric and 2MASS J , H , and Ks data allowed us to estimate the masses an...
متن کاملIonization toward the high-mass star-forming region NGC 6334 I⋆
Context. Ionization plays a central role in the gas-phase chemistry of molecular clouds. Since ions are coupled with magnetic fields, which can in turn counteract gravitational collapse, it is of paramount importance to measure their abundance in star-forming regions. Aims. We use spectral line observations of the high-mass star-forming region NGC 6334 I to derive the abundance of two of the mo...
متن کاملSubmillimeter Array Observations of the Molecular Outflow in High-mass Star-forming Region G240.31+0.07
We present Submillimeter Array observations toward the 10 L⊙ starforming region G240.31+0.07, in the J = 2–1 transition of CO and CO and at 1.3 mm continuum, as well as the CO and CO observations from the Caltech Submillimeter Observatory to recover the extended emission filtered out by the interferometer. Maps of the CO and CO emission show a bipolar, wide-angle, quasi-parabolic molecular outf...
متن کاملSubarcsecond Imaging of the High-mass Star Forming Region Onsala
We report subarcsecond images of the high-mass star forming region Onsala 1 (ON 1) made with the Submillimeter Array (SMA) at 0.85 mm and the Very Large Array at 1.3 cm and 3.6 cm. ON 1 is one of the smallest ultracompact H II regions in the Galaxy and exhibits various star formation signposts. With our VLA and SMA observations, two new cm-wave sources and five sub-mm dust sources, respectively...
متن کاملProper Motions of Thermal Radio Sources near Hh 7-11 in the Ngc 1333 Star Forming Region
Star forming regions are expected to show linear proper motions due to the relative motion of the Sun with respect to the region. These proper motions appear superposed to the proper motions expected in features associated with mass ejection from the young stellar objects embedded in them. Therefore, it is necessary to have a good knowledge of the proper motions of the region as a whole in orde...
