Exploring the Potential of Integral Field Spectroscopy Observing Extrasolar Planet Transits: Ground Based Observations of the Atmospheric Na in HD209458b
Santiago Arribas, Ronald L. Gilliland, William B. Sparks +4
We explore the use of Integral Field Spectroscopy (IFS) to observe extrasolar planet transits. Although this technique should find its full potential in space observations (e.g. JW…

IRAS 04000+5052: A not so compact, not so metal-poor HII region
Cesar Esteban, Luis Lopez-Martin, Angel R. Lopez-Sanchez +2
We present new observations of IRAS 04000+5052, a Galactic HII region associated with a young stellar cluster and possibly located at the Perseus arm. Contrary to previous claims,…
