We present the preliminary results derived from the MISMA inversion of Stokes I and V profiles of FeI 630.1nm FeI 630.2nm lines observed with: 1. SOT/SP instrument aboard the HINODE satellite. 2. IBIS in spectropolarimetric mode imaging, supported by simultaneous white light and G-band images, for blind deconvolution reconstruction. The complete

The transiting extrasolar planet XO-3b is remarkable, with a high mass and eccentric orbit. These unusual characteristics make it interesting to test whether its orbital plane is parallel to the equator of its host star, as it is observed for other transiting planets. We performed radial velocity measurements of XO-3 with the SOPHIE spectrograph at

Recent observations of coronal holes with Hinode show with unprecedented detail the launching of fast and hot jets. Many of these jets are found to coincide with the emergence of new magnetic flux, and it is generally assumed that the jets are initiated by magnetic reconnection between the new emerging flux and the existing open magnetic field

This article summarizes results of studies presented in two papers already published: Lites et al. (2007a); Lites et al. (2007b). Please see these for further details.

This is a progress report on a project to characterize the surface composition (and other properties such as radius, albedo and thermal inertia) of a sample of low perihelion Near-Earth Asteroids (NEAs), using spec-troscopy in the 0.3 to 2.5 micron region (groundbased) and in the 7 to 14 micron region (Spitzer). NEAs with low perihelion distances
