The Initial Mass Function of the Orion Nebula Cluster across the H-burning limit

Nicola Da Rio, Massimo Robberto, Lynne A. Hillenbrand +2

We present a new census of the Orion Nebula Cluster (ONC) over a large field of view (>30'x30'), significantly increasing the known population of stellar and substellar cluster mem…

Resolving the inner regions of the HD97048 circumstellar disk with VLT/NACO polarimetric differential imaging

Sascha P. Quanz, Stephan M. Birkmann, Daniel Apai +2

Circumstellar disks are the cradles of planetary systems and their physical and chemical properties directly influence the planet formation process. As most planets supposedly form…

Dust processing in Supernova Remnants: Spitzer MIPS SED and IRS Observations

M. Andersen, J. Rho, W. T. Reach +2

We present Spitzer MIPS SED and IRS observations of 14 Galactic Supernova Remnants previously identified in the GLIMPSE survey. We find evidence for SNR/molecular cloud interaction…

Pre--Main-Sequence stellar populations across Shapley Constellation III. I. Photometric Analysis and Identification

Dimitrios A. Gouliermis, Andrew E. Dolphin, Massimo Robberto +11

We present our investigation of pre--main-sequence (PMS) stellar populations in the Large Magellanic Cloud (LMC) from imaging with Hubble Space Telescope WFPC2 camera. Our targets…

On the lifetime of discs around late type stars

Barbara Ercolano, Nate Bastian, Loredana Spezzi +1

We address the question of whether protoplanetary discs around low mass stars (e.g. M-dwarfs) may be longer lived than their solar-type counterparts. This question is particularly…

Deep wide-field near-infrared survey of the Carina Nebula

Thomas Preibisch, Thorsten Ratzka, Benjamin Kuderna +7

(abbreviated) We used HAWK-I at the ESO VLT to produce a near-infrared survey of the Carina Nebula that is deep enough to detect the full low-mass stellar population. The results o…
