TLDR
In this paper, the authors describe how huge amounts of data produced by sky surveys from the ground and in space will eventually merge into a multi-wavelength virtual sky, and in many cases, astronomers will make more efficient "observations" through their computer terminal accessing databases rather than at a telescope.Abstract:
Considerable changes are under way in the practice of observational astronomy due to the improvements of panoramic detectors, the increasing archiving capacity of computers and the acceleration of communication networks. The huge amounts of data produced by sky surveys from the ground and in space will eventually merge into a multiwavelength virtual sky, and in many cases, astronomers will make more efficient “observations” through their computer terminal accessing databases rather than at a telescope.read more

M (sub)Dwarf Model Atmospheres: The Next Generation
TL;DR: In this paper, the authors present state-of-the-art molecular and atomic line-blanketed convective model atmospheres of cool low-mass stars, characterised by a thick convective zone reaching optical depths as low as τ ~ 10-3 and a nearly adiabatic temperature gradient.
