By analyzing high-resolution spectra for 11 red giant branch (RGB) stars, astronomers have conducted a chemical investigation of the globular cluster NGC 6723. Results of the study, presented in a paper published June 24 ...
By conducting photometric observations of the open cluster Stock 8 and its surrounding region, astronomers have identified 130 short-period variable stars, classifying 51 of them as members of the cluster. A paper detailing ...
Dying stars that cast off their outer envelopes to form the beautiful yet enigmatic "planetary nebulae" (PNe) have a new heavy-weight champion, the innocuously named PNe BMP1613-5406. Massive stars live fast and die young, ...
