Subrahmanyan Chandrasekhar (1910–1995) was one of the most important figures of 20th–Century astrophysics. The closing of Yerkes Observatory by the University of Chicago in 2018 led to discovery in Chandrasekhar's old Yerkes office of several box

We have investigated the past light history of the luminous variable star GR 290 (M33/V532, Romano’s Star) in the M33 galaxy, and collected new spectrophotometric observations in order to analyze links between this object, the LBV category, and the

Light curves in the B, V, and I_c passbands have been obtained for the type II Cepheids V154 in M3 and V42 and V84 in M5. Alternating cycle behavior, similar to that seen among RV Tauri variables, is confirmed for V84. Old and new observations, spann

UBVRCIC photometry of the W UMa eclipsing binary FI Bootis has been obtained and analyzed simultaneously with previously published photometry and radial velocities. The analysis of the light and radial velocity curves shows that the system is an A-ty

New UBVRI photometry has been obtained for the W UMa eclipsing system AM Leonis. The data have been used to derive nine times of minimum and to construct light curves. The minimum timings show that the system recently had a significant period increas

Photoelectric and photographic UBVRI photometry is presented for 104 of the brighter stars in the field of the globular cluster M13 (NGC 6205). The observed objects include the known variable stars of the cluster, suspected variables, and a number of

An attempt has been made to spatially resolve the metal-poor, double-lined spectroscopic binary HD 20039 with the Hubble Space Telescope Fine Guidance System. Astrometric measurements of the system to complement the spectroscopic orbit would permit t

— A 0.5 kg stony meteorite associated with a bright bolide seen over southeastern Michigan on 1994 October 20 has been recovered. The circumstances of the fall and recovery of this chondrite, named Coleman, are presented. The most likely trajectory
