Remarks on Rapid vs. Slow Star Formation
TL;DR: In this article, the authors discuss problems with some observational estimates indicating long protostellar core lifetimes and large stellar age spreads in molecular clouds, and point out some additional observational constraints which suggest that the core does not have long lifetimes before collapsing, and argue that the rapid star formation indicated observationally is easier to understand theoretically than the traditional scenario of slow quasi-static contraction with ambipolar diffusion.

Chromospheres in metal deficient field stars
TL;DR: In this paper, a systematic program to assess the presence and character of chromospheric line profiles and their variations, and to obtain quantitative measurements of radiative losses from chromospheres is presented.
