OGLE2-TR-L9: An extrasolar planet transiting a fast-rotating F3 star
I. A. G. Snellen, J. Koppenhoefer, R. F. J. van der Burg +7
Context: Photometric observations for the OGLE-II microlens monitoring campaign have been taken in the period 1997-2000. All light curves of this campaign have recently been made p…
Two-component galaxy models: the effect of density profile at large radii on the phase-space consistency
Luca Ciotti, Lucia Morganti
It is well known that the density and anisotropy profile in the inner regions of a stellar system with positive phase-space distribution function are not fully independent. Here we…
Kinematics of the old stellar population at the Galactic Center
S. Trippe, S. Gillessen, O. E. Gerhard +8
We aim at a detailed description of the kinematic properties of the old, (several Gyrs) late-type CO-absorption star population among the Galactic centre (GC) cluster stars. We app…
Secular Evolution in Disk Galaxies: Pseudobulge Growth and the Formation of Spheroidal Galaxies
John Kormendy, David B. Fisher
Updating Kormendy & Kennicutt (2004, ARAA, 42, 603), we review internal secular evolution of galaxy disks. One consequence is the growth of pseudobulges that often are mistaken for…
Bulges of disk galaxies at intermediate redshifts. I. Samples with and without bulges in the Groth Strip Survey
L. Dominguez-Palmero, M. Balcells, P. Erwin +4
We aim to define a sample of intermediate-z disk galaxies harbouring central bulges, and a complementary sample of disk galaxies without measurable bulges. We intend to provide col…
The radii of the nearby K5V and K7V stars 61 Cyg A & B - CHARA/FLUOR interferometry and CESAM2k modeling
Pierre Kervella, Antoine Mérand, Bernard Pichon +11
Context: The main sequence binary star 61 Cyg (K5V+K7V) is our nearest stellar neighbour in the northern hemisphere. This proximity makes it a particularly well suited system for v…
