THE DISK-OUTFLOW SYSTEM IN THE S255IR AREA OF HIGH-MASS STAR FORMATION [PDF]

, 2015
We report the results of our observations of the S255IR area with the Submillimeter Array (SMA) at 1.3 mm in the very extended configuration and at 0.8 mm in the compact configuration as well as with the IRAM 30 m at 0.8 mm.

Kuiper belts around nearby stars [PDF]

, 2010
Context. The existence of dusty debris disks around a large fraction of solar type main-sequence stars, inferred from excess far-IR and submillimetre emission compared to that expected from stellar photospheres, suggests that leftover planetesimal belts ...

VIS: the visible imager for Euclid [PDF]

Other Conferences, 2012
Euclid-VIS is a large format visible imager for the ESA Euclid space mission in their Cosmic Vision program, scheduled for launch in 2019. Together with the near infrared imaging within the NISP instrument it forms the basis of the weak lensing ...

Absorption features in the spectra of X-ray bursting neutron stars [PDF]

, 2008
Context. The discovery of photospheric absorption lines in XMM-Newton spectra of the X-ray bursting neutron star in EXO 0748−676 by Cottam and collaborators allows us to constrain the neutron star mass-radius ratio from the measured gravitational ...

MAGNETIZED NEUTRON STAR ATMOSPHERES: BEYOND THE COLD PLASMA APPROXIMATION [PDF]

, 2011
All the neutron star (NS) atmosphere models published so far have been calculated in the “cold plasma approximation,” which neglects the relativistic effects in the radiative processes, such as cyclotron emission/absorption at harmonics of cyclotron ...

E-prints and Journal Articles in Astronomy: a Productive Co-existence

, 2006
Are the e-prints (electronic preprints) from the arXiv repository being used instead of the journal articles? In this paper we show that the e-prints have not undermined the usage of journal papers in the astrophysics community.

BD–22°3467, a DAO-type star exciting the nebula Abell 35 [PDF]

, 2012
Context. Spectral analyses of hot, compact stars with non-local thermodynamical equilibrium (NLTE) model-atmosphere techniques allow the precise determination of photospheric parameters such as the effective temperature (Teff), the surface gravity (log g)
