Description
Light curves of the very low-mass member of the alpha Persei open cluster, AP J0323+4853, obtained during two different observing runs in 1994 and 1995, display a starspot rotational modulation of period ~7.6h. With a most likely mass of 0.09 Msolar, close to the substellar limit, AP J0323+4853 is the lowest mass star so far for which a photometric rotation period has been derived.

    Context. High-contrast imaging observations mostly rely on angular differential imaging, a successful technique for detecting point-sources, such as planets. However, in the vicinity of the star (typically below 300 mas), this technique suffers from signal self-subtraction when there is not enough field rotation. Building large libraries of

    Hints of auroral and magnetospheric polarized radio emission from the scallop-shell star 2MASS J05082729–2101444
    Scallop-shell stars, a recently discovered class of young M dwarfs, show complex optical light curves that are characterized by periodic dips as well as other features that are stable over tens to hundreds of rotation cycles. The origin of these features is not well-understood. 2MASS J05082729‑2101444 is a ∼25 Myr old scallop-shell star that was

    Assessing your Observatory's Impact: Best Practices in Establishing and Maintaining Observatory Bibliographies
    Observatories need to measure and evaluate the scientific output and overall impact of their facilities. An observatory bibliography consists of the papers published using that observatory's data, typically gathered by searching the major journals for relevant keywords. Recently, the volume of literature and methods by which the publications pool
