Coronae in the Coronet: a very deep X-ray look into a stellar nursery

  title={Coronae in the Coronet: a very deep X-ray look into a stellar nursery},
  author={Jan Forbrich and Th. Henning MPIfR Bonn and Aiu Jena},
  journal={Astronomy and Astrophysics},
Aims. To study the X-ray properties of young stellar objects (YSOs), we analyze an exceptionally sensitive Chandra dataset of the Coronet cluster in the CrA star-forming region, achieving a limiting luminosity of $L_{\rm X,min} \sim 5\times 10^{26}$ erg/s for lightly absorbed sources. This dataset represents one of the most sensitive X-ray observations ever obtained of a star-forming region. Methods. The X-ray data are used to investigate the membership status of tentative members of the region… Expand
Near-infrared Properties of the X-ray-emitting Young Stellar Objects in the Carina Nebula
The Great Nebula in Carina (NGC 3372) is the best target to study in detail the process of violent massive star formation and the resulting feedback effects of cloud dispersal and triggered starExpand

Abstract In the last few years, X-ray observational studies of young star clusters have advanced significantly, mainly thanks to the great capabilities of current X-ray observatories such as ChandraExpand
Star Formation in Orion's L1630 Cloud: An Infrared and Multi-epoch X-Ray Study
X-ray emission is characteristic of young stellar objects (YSOs) and is known to be highly variable. We investigate, via an infrared and multi-epoch X-ray study of the L1630 dark cloud, whether andExpand
Discovery of x-ray emission from young suns in the small magellanic cloud
We report the discovery of extended X-ray emission within the young star cluster NGC 602a in the Wing of the Small Magellanic Cloud (SMC) based on observations obtained with the Chandra X-RayExpand
High-energy processes in low-mass protostars - an X-ray to radio multi-wavelength perspective
High-energy processes in protostars remain poorly understood. Only after the recently finished Chandra Orion Ultra-deep Project (COUP), statistically significant information on X-ray emission fromExpand
Radio continuum imaging of the R Coronae Austrinae star-forming region with the ATCA
Aims. The aim of this study is to investigate the nature of radio sources associated with young stellar objects (YSOs) belonging to the R CrA cluster. By combining the centimetre radio data with theExpand
Young stellar objects (YSOs) and in particular protostars are known to show a variety of high-energy processes. Observations in the X-ray and centimetric radio wavelength ranges are thought toExpand
Very Low Mass Objects in the Coronet Cluster: The Realm of the Transition Disks*
We present optical and IR spectra of a set of low-mass stars and brown dwarfs in the Coronet cluster (aged ~1 Myr), obtained with the multifiber spectrograph FLAMES on the VLT and with the IRSExpand
Protostars and Stars in the Coronet Cluster: Age, Evolution, and Cluster Structure
We present new optical spectroscopy with the FLAMES spectrograph at the Very Large Telescope (VLT), near-IR imaging with VLT/HAWK-I, and 870 {mu}m mapping with APEX/LABOCA of the Coronet cluster. TheExpand
Revealing the "missing" low-mass stars in the S254-S258 star forming region by deep X-ray imaging ?
Context. X-ray observations provide a very good way to reveal the population of young stars in star forming regions avoiding the biases introduced when selecting samples based on infrared excess.Expand


Simultaneous X-ray, radio, near-infrared and optical monitoring of young stellar objects in the Coronet cluster
Context. Multi-wavelength (X-ray to radio) monitoring of Young Stellar Objects (YSOs) can provide important information about physical processes at the stellar surface, in the stellar corona, and/orExpand
An X-ray superflare are from an infrared protostar
Class I protostars1 are very young, low-mass stellar objects that are, according to current models, composite: they include a central star (still in the process of formation) surrounded by anExpand
X-Ray Emission from Young Brown Dwarfs in the Orion Nebula Cluster
We use the sensitive X-ray data from the Chandra Orion Ultradeep Project (COUP) to study the X-ray properties of 34 spectroscopically identified brown dwarfs with near-infrared spectral types betweenExpand
X-Ray Properties of the Young Stellar and Substellar Objects in the IC 348 Cluster: The Chandra View
We explore the X-ray properties of the young stellar and substellar objects in the open cluster IC 348 as seen in our deep Chandra X-Ray Observatory Advanced CCD Imaging Spectrometer image. First, weExpand
