The co-existence of hot and cold gas in debris discs
I. Rebollido, C. Eiroa, B. Montesinos +19
Debris discs have often been described as gas-poor discs as the gas-to-dust ratio is expected to be considerably lower than in primordial,protoplanetary discs. However, recent obse…
Searching for signatures of planet formation in stars with circumstellar debris discs
J. Maldonado, C. Eiroa, E. Villaver +2
(Abridged) Tentative correlations between the presence of dusty debris discs and low-mass planets have been presented. In parallel, detailed chemical abundance studies have reporte…
Potential multi-component structure of the debris disk around HIP 17439 revealed by Herschel/DUNES
S. Ertel, J. P. Marshall, J. -C. Augereau +16
[abridged] Aims. Our Herschel Open Time Key Programme DUNES aims at detecting and characterizing debris disks around nearby, sun-like stars. In addition to the statistical analysis…
Comparative Modelling of the Spectra of Cool Giants
T. Lebzelter, U. Heiter, C. Abia +24
Our ability to extract information from the spectra of stars depends on reliable models of stellar atmospheres and appropriate techniques for spectral synthesis. Various model code…
A Herschel resolved far-infrared dust ring around HD 207129
J. P. Marshall, T. Löhne, B. Montesinos +26
Dusty debris discs around main sequence stars are thought to be the result of continuous collisional grinding of planetesimals in the system. The majority of these systems are unre…
Gas in Protoplanetary Discs (GASPS) 1. First results
G. S. Mathews, W. R. F. Dent, J. P. Williams +50
Context - Circumstellar discs are ubiquitous around young stars, but rapidly dissipate their gas and dust on timescales of a few Myr. The Herschel space observatory allows for the…
