Probing interstellar extinction near the 30 Doradus nebula with red giant stars
Guido De Marchi, Nino Panagia, Leo Girardi
We have studied the interstellar extinction in a field of 3' x 3' located about 6' SW of 30 Doradus in the Large Magellanic Cloud (LMC). Hubble Space Telescope observations in the…
Hα photometry of low mass stars in 47 Tucanae: chromospheric activity and exotica
G. Beccari, G. De Marchi, N. Panagia +1
We have used archival Hubble Space Telescope observations obtained with the Advanced Camera for Surveys to study the Hα emission properties of main sequence stars in the globular c…
The state of globular clusters at birth: emergence from the gas-embedded phase
Nathan W. C. Leigh, Mirek Giersz, Jeremy J. Webb +4
In this paper, we discuss the origin of the observed correlation between cluster concentration c and present-day mass function (PDMF) slope α reported by De Marchi, Paresce & Pulon…
Pre-main sequence stars older than 8 Myr in the Eagle Nebula
Guido De Marchi, Nino Panagia, M. G. Guarcello +1
Attention is given to a population of 110 stars in the NGC 6611 cluster of the Eagle Nebula that have prominent near-infrared (NIR) excess and optical colours typical of pre-main s…
Photometric determination of the mass accretion rate of pre-main sequence stars. IV. Recent star formation in NGC 602
Guido De Marchi, Giacomo Beccari, Nino Panagia
We have studied the young stellar populations in NGC 602, in the Small Magellanic Cloud, using a novel method that we have developed to combine Hubble Space Telescope photometry in…
Accurate determination of accretion and photospheric parameters in Young Stellar Objects: the case of two candidate old disks in the Orion Nebula Cluster
C. F. Manara, G. Beccari, N. Da Rio +5
Current planet formation models are largely based on the observational constraint that protoplanetary disks have lifetime 3Myr. Recent studies, however, report the existence of PMS…
Hubble Tarantula Treasury Project: Unraveling Tarantula's Web. I. Observational overview and first results
E. Sabbi, J. Anderson, D. J. Lennon +18
The Hubble Tarantula Treasury Project (HTTP) is an ongoing panchromatic imaging survey of stellar populations in the Tarantula Nebula in the Large Magellanic Cloud that reaches int…
