Spectra, Flares, and Mass Loss from the dMe star, Ross 154
We present results from a Chandra observation of Ross 154, a nearby (2.93 pc) flaring M dwarf (M4.5Ve). During the 57-ksec ACIS-S exposure, a very large flare...
Spectral analysis and mineralogical characterization of 11 olivine pyroxene rich NEAs
We present visible and near-infrared spectra (0.5 2.4 μm) of 11 Near Earth Asteroids obtained with the telescopes at the “Observatorio del Roque de los...
Spectral and mineralogical characterization of NEOs
Using the NOT, WHT and TNG telescopes located at Observatorio del Roque de los Muchachos (Canary Islands, Spain) we have obtained low resolution visible and...
Spectral and spectro-photometric characterization of NEOs at the Canary Islands Observatories
The population of near-Earth objects (NEOs) shows a large variety of physical and dynamical properties. Their study is relevant for the science of planetary...
Spectral characterization of near-Earth asteroids on cometary orbits
A fraction of near-Earth asteroids has the orbital elements similar to those of comets, but a visual aspect as any other point-like source. These are...
Spectral Chracterization of Microvariability in Quasars
These are the preliminary results of our BVR photometric study. The quasar 1628.5+3808 is shown here only for the sake of illustration of our research. This...
Spectral Classification and Physical Parameters of Be Stars in the Perseus Arm with the BCD System
IPHAS (the INT/WTC Photometric Ha Survey of the Northern Galactic Plane, www.iphas.org) is a survey carried out, in H-α, r and i filters, with the Wide Field...
Spectral clustering tools applied to Ceres in preparation for the NASA OSIRIS-REx images of (101955) Bennu
NASA's OSIRIS-REx mission is currently on its way to the asteroid (101955) Bennu. Bennu is a primitive asteroid, characterized by a dark surface composed mainly...
