Estimating the Age of Exoplanet Host Stars: Possible Member of the Hyades Supercluster Confirmed by Chemically Tagging
During our detailed study of the kinematics of the know exoplanets hots stars (Montes et al. 2010, Caballero et al. 2010) we have identified possible members of...
Estimating the size and abundance of dark matter subhaloes with gravitational millilensing
We use 8 gravitational lens systems with quadruply imaged quasars and their observed flux ratio anomalies obtained using data in mid-infrared, radio or spectral...
Estimation of a possible time variation of the electron mass from CMB observations
We study the effects of a possible joint variation of the electron mass and the fine structure constant on the CMBR temperature fluctuation spectrum. We use the...
Estimation of adaptive optics parameters from wind speed: results for the Teide Observatory
The development of adaptive optics systems for projects related to large telescopes demands a proper knowledge of the atmospheric turbulence. Due to the lack of...
Estimation of Cosmological Parameters from CMB data, including a possible time variation of the electron mass and the fine structure constant
The variation of some fundamental constants of nature is a prediction of several unifying theories. As physics at recombination is sensitive to the value of the...
Estimation of Elemental Abundances, Temperatures, and Surface Gravities for SDSS Stellar Spectra
Discovery of the true nature of the halo of the Galaxy has long been limited by the number of stars with available spectroscopy and photometry. This constraint...
Estimation of H_0 from photometric monitoring of QSO 0957+561
The Hubble constant can be measured from the time delay between pairs of components of a multiply-imaged quasar, depending only on the mass model and the...
