Report by the ESA-ESO Working Group on Extra-Solar Planets
M. Perryman, O. Hainaut, D. Dravins +14
Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) displacements, grav…
Gaia predicted brown dwarf detection rates around FGK stars in astrometry, radial velocity, and photometric transits
B. Holl, M. Perryman, L. Lindegren +2
Context: The current sample of known brown dwarfs (BDs) around FGK-stars is only of the order of a hundred. The ongoing ESA mission Gaia has already collected its nominal 5 yr of m…
The Dark Universe is not invisible
K. Zioutas, V. Anastassopoulos, A. Argiriou +18
Dark matter (DM) comes from long-range gravitational observations, and it is considered as something that does not interact with ordinary matter or emits light. However, also on mu…
Spectroscopic survey of the Galaxy with Gaia I. Design and performance of the Radial Velocity Spectrometer
D. Katz, U. Munari, M. Cropper +22
The definition and optimisation studies for the Gaia satellite spectrograph, the Radial Velocity Spectrometer (RVS), converged in late 2002 with the adoption of the instrument base…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects
Gaia Collaboration, F. van Leeuwen, A. Vallenari +589
Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry,…
Gaia Radial Velocity Spectrometer
M. Cropper, D. Katz, P. Sartoretti +40
This paper presents the specification, design, and development of the Radial Velocity Spectrometer (RVS) on the European Space Agency's Gaia mission. Starting with the rationale fo…
High-speed energy-resolved STJ photometry of the eclipsing dwarf nova IY UMa
D. Steeghs, M. Perryman, A. Reynolds +4
We present high time-resolution photometry of the dwarf nova IY UMa using the S-Cam2 super-conducting tunnel junction device attached to the 4.2m William Herschel Telescope on La P…
