Spectroscopy of Brown Dwarf Candidates in the NGC 1333 Molecular Cloud
We present an analysis of low-resolution infrared spectra for 25 brown dwarf candidates in the NGC 1333 molecular cloud. Candidates were chosen on the basis of their association with the high column density cloud core, and near-infrared fluxes and colors. We compare the depths of water vapor absorption bands in our candidate objects with a grid of dwarf, subgiant, and giant standards to determi...
متن کاملObservations of NGC 1333 : The Ratio of Stars to Sub - stellar Objects
We present an analysis of NICMOS photometry and low-resolution grism spectroscopy of low-mass stars and sub-stellar objects in the young star-forming region NGC 1333. Our goal is to constrain the ratio of low-mass stars to substellar objects down to 20 MJup in the cluster as well as constrain the cluster
متن کاملBroad band infrared spectroscopy of massive young stellar objects
We present intermediate resolution 0.9–2.5μm IR spectra of 12 highly reddened stars, including some well known and some unfamiliar sources. A new technique for extracting calibration curves from standard star data is employed, and is found to be very successful. The reddening to each object is fully discussed and is calculated from both the continua (which was split into shortand long-wavelengt...
متن کاملNear - Infrared Spectroscopy of Molecular Hydrogen Emission in Four Reflection Nebulae : NGC 1333 , NGC 2023 , NGC 2068 , and NGC 7023
We present near-infrared spectroscopy of fluorescent molecular hydrogen (H2) emission from NGC 1333, NGC 2023, NGC 2068, and NGC 7023 and derive the physical properties of the molecular material in these reflection nebulae. Our observations of NGC 2023 and NGC 7023 and the physical parameters we derive for these nebulae are in good agreement with previous studies. Both NGC 1333 and NGC 2068 hav...
متن کاملProper Motions of Young Stellar Outflows in the Mid-infrared with Spitzer (irac). I. the Ngc 1333 Region
We use two 4.5μm Spitzer (IRAC) maps of the NGC 1333 region taken over a ∼ 7 yr interval to determine proper motions of its associated outflows. This is a first, successful attempt at obtaining proper motions of stellars outflow from Spitzer observations. For the outflow formed by the HerbigHaro objects HH7, 8 and 10, we find proper motions of ∼ 9-13 km s−1, which are consistent with previously...
