Exploring aspects of scientific publishing in astrophysics and cosmology: the views of scientists

Scientists in astrophysics and cosmology make much use of the arXiv repository. Concerns raised by scientists in those fields about publication costs and delays, and the transparency and validity of the peer review process, raised questions about levels of satisfaction with existing publishing models. This paper discusses the results from a community survey in the fields of astrophysics and cos...

Astronomy and Astrophysics Astronomical Seeing from the Summits of the Antarctic Plateau

From the South Pole, microthermal turbulence within a narrow surface boundary layer some 200 m thick provides the dominant contribution to the astronomical seeing. We present results for the seeing at a wavelength of 2.4µm. The narrow turbulence layer above the site, confined close to the surface, provides greatly superior conditions for adaptive optics correction than do temperate latitude sit...

Astrophysics.

Using the oscillation frequencies of α Cen A recently discovered by Bouchy & Carrier (2001, 2002), the available astrometric, photometric and spectroscopic data, we tried to improve the calibration of the visual binary system α Cen. With the revisited masses of Pour-baix et al. (2002) we do not succeed to obtain a solution satisfying all the seismic observational constraints. Relaxing the const...

Repository Interface for Overlaid Journal Archives (RIOJA): a feasibility study reporting the views of scientists in astrophysics and cosmology

This paper discusses the preliminary results from an online questionnaire survey of scientists in the fields of astrophysics and cosmology, conducted as part of an investigation into the feasibility of the "overlay journal" model in these disciplines. Six hundred and eighty three (683) researchers provided information about their academic background, their research practices, and their attitude...
