Magnetotelluric Sounding of Terrestrial Planet and Satellite Interiors
Introduction. Electromagnetic (EM) sounding of the Moon and the Galilean satellites has yielded important insights on the interior structures of these bodies [e.g., 1-7]. These investigations measured magnetic fields only and required auxiliary information on the nature of the source fields. The magnetotelluric (MT) method, by measuring both magnetic and electric fields, can perform soundings f...
متن کاملSequestration of noble gases in giant planet interiors.
The Galileo probe showed that Jupiter's atmosphere is severely depleted in neon compared to protosolar values. We show via ab initio simulations of the partitioning of neon between hydrogen-helium phases that the observed depletion can be explained by the sequestration of neon into helium-rich droplets within the postulated hydrogen-helium immiscibility layer of the planets interior. We also de...
متن کاملMeasurements of Stellar Inclinations for Kepler Planet Candidates
We present an investigation of spin-orbit angles for planetary system candidates reported by Kepler. By combining the rotational period Ps inferred from the flux variation due to starspots and the projected rotational velocity V sin Is and stellar radius obtained by a high resolution spectroscopy, we attempt to estimate the inclination Is of the stellar spin axis with respect to the line-of-sig...
متن کاملThe XO Project: Searching for Transiting Extra-solar Planet Candidates
The XO project’s first objective is to find hot Jupiters transiting bright stars, i.e. V < 12, by precision differential photometry. Two XO cameras have been operating since September 2003 on the 10,000-foot Haleakala summit on Maui. Each XO camera consists of a 200-mm f/1.8 lens coupled to a 1024x1024 pixel, thinned CCD operated by drift scanning. In its first year of routine operation, XO has...
متن کاملSelect the Best Planet Candidates for Mass Follow - up
A unique analytical solution of planet and star parameters can be derived from an extrasolar planet transit light curve under a number of assumptions. This analytical solution can be used to choose the best planet transit candidates for radial velocity follow-up measurements, with or without a known spectral type. In practice, high photometric precision (< 0.005 mag) and high time sampling (< 5...
