Spitzer Secondary Eclipses of the Dense, Modestly-irradiated, Giant Exoplanet HAT-P-20b Using Pixel-Level Decorrelation
Drake Deming, Heather Knutson, Joshua Kammer +13
HAT-P-20b is a giant exoplanet that orbits a metal-rich star. The planet itself has a high total density, suggesting that it may also have a high metallicity in its atmosphere. We…
Spitzer/IRAC Observations of the Variability of Sgr A* and the Object G2 at 4.5 microns
J. L. Hora, G. Witzel, M. L. N. Ashby +9
We present the first detection from the Spitzer Space Telescope of 4.5 micron variability from Sgr A*, the emitting source associated with the Milky Way's central black hole. The >…
The pros and cons of the inversion method approach to derive 3D dust emission properties of the ISM: the Hi-GAL field centred on (l,b)=(30,0)
Alessio Traficante, Roberta Paladini, Mathieu Compiegne +13
Herschel FIR continuum data obtained as part of the Hi-GAL survey have been used, together with the GLIMPSE 8 m and MIPSGAL 24 m data, to attempt the first 3D-decomposition o…
