A detailed census of variable stars in the globular cluster NGC 6333 (M9) from CCD differential photometry
A. Arellano Ferro, D. M. Bramich, R. Figuera Jaimes +37
We report CCD and time-series photometry of the globular cluster NGC 6333 (M9). The technique of difference image analysis has been used, which enables photometric precisio…
Estimating the parameters of globular cluster M 30 (NGC 7099) from time-series photometry
N. Kains, D. M. Bramich, A. Arellano Ferro +47
We present the analysis of 26 nights of V and I time-series observations from 2011 and 2012 of the globular cluster M 30 (NGC 7099). We used our data to search for variable stars i…
EMCCD photometry reveals two new variable stars in the crowded central region of the globular cluster NGC 6981
Jesper Skottfelt, D. M. Bramich, R. Figuera Jaimes +33
Two previously unknown variable stars in the crowded central region of the globular cluster NGC 6981 are presented. The observations were made using the Electron Multiplying CCD (E…
