The Hubble Deep Fields
Dickinson, Mark; Ferguson, Henry C.; Williams, Robert
The Hubble space telescope observations of the northern Hubble deep field, and more recently its counterpart in the south, provide detections and photometry for stars and field galaxies to the faintest levels currently achievable, reaching magnitudes V ~ 30. Since 1995, the northern Hubble deep field has been the focus of deep surveys at nearly al…
Stellar Structure and Evolution: Deductions from Hipparcos
Lebreton, Yveline
During the last decade, the understanding of fine features of the structure and evolution of stars has become possible as a result of enormous progress made in the acquisition of high-quality observational and experimental data, and of new developments and refinements in the theoretical description of stellar plasmas. The confrontation of high-qua…
