Earthshine Observations of an Inhabited Planet
Earthshine is sunlight that has been reflected from the dayside Earth onto the dark side of the Moon and back again to Earth. In recent times, there has been renewed interest in ground-based visible and near-infrared measurements of earthshine as a proxy for exoplanet observations. Observations of earthshine allow us to explore and characterize the globally integrated photometric, spectral and ...
متن کاملSALT observations of the Chromospheric Activity of Transiting Planet Hosts: Mass Loss and Star Planet Interactions
We measured the chromospheric activity of the four hot Jupiter hosts WASP-43, WASP-51/HAT-P-30, WASP-72 & WASP-103 to search for anomalous values caused by the close-in companions. The Mount Wilson Ca ii H&K S -index was calculated for each star using observations taken with the Robert Stobie Spectrograph at the Southern African Large Telescope. The activity level of WASP-43 is anomalously high...
متن کاملDiscovery and spectroscopy of the young jovian planet 51 Eri b with the Gemini Planet Imager.
Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric compositions and luminosities, which are influenced by their formation mechanisms. Using the Gemini Planet Imager, we discovered a planet orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units. Near-infrared observations show a spectrum with str...
متن کاملA retrospective review of 139 major and minor salivary gland tumors.
AIM To describe demographic and histomorphological characteristics of 139 patients with epithelial salivary gland tumors in the Southeastern Serbia population. METHODS A total number of 139 patients with epithelial tumors arising in major and minor salivary glands in the period 2010-2012 was evaluated. After standard tissue proceeding, the routine haematoxylin-eosin (HE) and histochemical alc...
متن کاملMassive Planet Migration: Theoretical Predictions and Comparison with Observations
We quantify the utility of large radial velocity surveys for constraining theoretical models of Type II migration and protoplanetary disk physics. We describe a theoretical model for the expected radial distribution of extrasolar planets that combines an analytic description of migration with an empirically calibrated disk model. The disk model includes viscous evolution and mass loss via photo...
