Systematics of the Ultraviolet Rising flux in a GALEX/SDSS sample of Early-type Galaxies
R. M. Rich, S. Salim, J. Brinchmann +24
We present ultraviolet photometry for a sample of morphologically early-type galaxies selected by matching the Sloan Digital Sky Survey Data Release 1 with the GALEX Medium and All…
The structure of Onsala 1 star forming region
M. S. N. Kumar, M. Tafalla, R. Bachiller
We present new high-sensitivity high-resolution mm-wave observations of the Onsala 1 ultra-compact HII region that bring to light the internal structure of this massive star formin…
Embedded Star Clusters in the W51 Giant Molecular Cloud
M. S. N. Kumar, U. S. Kamath, C. J. Davis
We present sub-arcsecond (0.35"-0.9"), near-infrared J,H,K band photometric observations of six fields along the W51 Giant Molecular Cloud (W51 GMC). Our observations reveal four n…
Present-Day Growth of Black Holes and Bulges: the SDSS Perspective
Timothy M. Heckman, Guinevere Kauffmann, Jarle Brinchmann +3
We investigate the accretion-driven growth of supermassive black holes in the low-redshift Universe using 23,000 ``Type 2'' AGN and the complete sample of 123,000 galaxies in the S…
The Origin of the Mass--Metallicity Relation: Insights from 53,000 Star-Forming Galaxies in the SDSS
C. A. Tremonti, T. M. Heckman, G. Kauffmann +9
We utilize Sloan Digital Sky Survey imaging and spectroscopy of ~53,000 star-forming galaxies at z~0.1 to study the relation between stellar mass and gas-phase metallicity. We deri…
The role of the time step and overshooting in the modelling of PMS evolution: the case of EK Cephei
J. P. Marques, J. Fernandes, M. J. P. F. G. Monteiro
We have produced detailed evolutionary models of the binary EK Cep using the CESAM stellar evolution code (Morel 1997). A -minimisation was performed to derive the most reliab…
Non-Random Phases in Non-Trivial Topologies
Patrick Dineen, Graca Rocha, Peter Coles
We present a new technique for constraining the topology of the universe. The method exploits the existence of correlations in the phases of the spherical harmonic coefficients of…
Asteroseismic Signatures of Helium gradients in Main-Sequence A Stars ; Application to the roAp Star HD60435
Sylvie Vauclair, Sylvie Theado
Asteroseismology is found to be a excellent tool for detecting diffusion-induced helium gradients inside main-sequence A stars. Models have been computed for 1.6 and 2.0 M$_{\odot}…
Photospheric magnetic field and surface differential rotation of the FK Com star HD 199178
P. Petit, J. -F. Donati, J. M. Oliveira +11
We present spectropolarimetric observations of the FK Com star HD 199178 obtained between 1998 December and 2003 August at the Telescope Bernard Lyot (Observatoire du Pic du Midi,…
Predicted rotation signatures in MHD disc winds and comparison to DG Tau observations
N. Pesenti, C. Dougados, S. Cabrit +4
Motivated by the first detections of rotation signatures in the DG Tau jet (Bacciotti et al. 2002), we examine possible biases affecting the relation between detected rotation sign…
Stellar polarimetry with ESPaDOnS
P. Petit, J. -F. Donati, The ESPaDOnS project team
ESPaDOnS is a new-generation cross-dispersed echelle spectropolarimeter, the commissioning phase of which is scheduled at the Canada-France-Hawaii Telescope (CFHT) for spring 2004.…
The Environmental Dependence of the Relations between Stellar Mass, Structure, Star Formation and Nuclear Activity in Galaxies
Guinevere Kauffmann, Simon D. M. White, Timothy M. Heckman +5
We use a complete sample of galaxies drawn from the SDSS to study how structure, star formation and nuclear activity depend on local density and on stellar mass. Local density is e…
Further Clues to the Nature of Composite LINER/HII Galaxies
M. E. Filho, F. Fraternali, S. Markoff +4
We have analyzed new, archival and published high resolution radio and X-ray observations of a sample of composite LINER/HII galaxies known to exhibit AGN-like properties. Five of…
Updated Toulouse solar models including the diffusion-circulation coupling and the effect of -gradients
O. Richard, S. Théado, S. Vauclair
New solar models are presented, which have been computed with the most recent physical inputs (nuclear reaction rates, equation of state, opacities, microscopic diffusion). Rotatio…
Estimating the bispectrum of the Very Small Array data
Sarah Smith, Graca Rocha, Anthony Challinor +30
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtaine…
