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

Trojan asteroids are an interesting population of minor bodies due to their dynamical characteristics, their physical properties and that they are relatively isolated located at the snow-line The main hypotheses about the origin of the Jupiter Trojans assumed that they formed either during the final stages of the planetary formation (Marzari &

The solar rotation profile is well constrained down to about 0.25 R &sun; thanks to the study of acoustic modes. Since the radius of the inner turning point of a resonant acoustic mode is inversely proportional to the ratio of its frequency to its degree, only the low-degree p modes reach the core. The higher the order of these modes, the deeper

Following the discovery of the new X-ray transient XTE J1637-498 (Atel #1699), we obtained a short (nearly 1 ksec) observation using the Swift/XRT in PC mode on 2008-09-04 at 18:15 UT. We detected one relatively bright source within the ~6 arcminutes PCA error circle at a position of RA=16:37:02.995, Dec=-49:51:37 (J2000), with an estimated
