THE DEARTH OF CHEMICALLY ENRICHED WARM-HOT CIRCUMGALACTIC GAS
X-ray absorption lines galaxy
2014/12/22
The circumgalactic medium (CGM) around galaxies is believed to record various forms of galaxy feedback and contain a significant portion of the "missing baryons" of individual dark matter halos. Howev...
Enriched haloes at redshift $z=2$ with no star-formation: Implications for accretion and wind scenarios
galaxies:evolution galaxies:formation galaxies:high-redshifts galaxies
2011/10/13
In order to understand which process (e.g. galactic winds, cold accretion) is responsible for the cool (T~10^4 K) halo gas around galaxies, we embarked on a program to study the star-formation propert...
The First Kepler Mission Planet Confirmed With The Hobby-Eberly Telescope: Kepler-15b, a Hot Jupiter Enriched In Heavy Elements
Hot Jupiter Enriched Heavy Elements Planet Confirmed
2011/10/9
We report the discovery of Kepler-15b, a new transiting exoplanet detected by NASA's Kepler mission. The transit signal with a period of 4.94 days was detected in the quarter 1 (Q1) Kepler photometry....
Li - O anti-correlation in NGC 6752: evidence for Li-enriched polluting gas
stars abundances – globular clusters individual NGC6752 – stars late-type
2010/11/11
Context. Elemental correlations and anti-correlations are known to be present in globular clusters (GCs) owing to pollution by CNO cycled gas. Because of its fragility Li is destroyed at the temperatu...
