Astrometry and photometry with HST-WFC3. I. Geometric distortion corrections of F225W, F275W, F336W bands of the UVIS-channel
A. Bellini, L. R. Bedin
An accurate geometric distortion solution for the Hubble Space Telescope UVIS-channel of Wide Field Camera 3 is the first step towards its use for high precision astrometry. In thi…

Hot Horizontal Branch stars in omega Centauri: clues about their origin from the cluster Color Magnitude Diagram
S. Cassisi, M. Salaris, J. Anderson +5
We investigate a peculiar feature at the hottest, blue end of the horizontal branch of Galactic globular cluster omega Centauri, using the high-precision and nearly complete catalo…
