In this second paper on cataclysmic variables detected in the Cal´an–Tololo Survey we present time-resolved spectroscopy for the remaining eight systems without a measured orbital period. We derive orbital periods for ...

In this second paper on cataclysmic variables detected in the Calán–Tololo Survey we present time-resolved spectroscopy for the remaining eight systems without a measured orbital period. We derive orbital periods for all ...

In a search for cataclysmic variables in the Calan-Tololo Survey, we have detected 21 systems, 16 of them previously unknown. In this paper we present detailed time-series photometry for those six confirmed cataclysmic ...

In this paper we summarize the known results on the possible sets of periods of homeomorphisms defined on some classes of finite connected compact graphs, and we present new results.

We explore the synergy between photometric and spectroscopic surveys by searching for periodic variable stars among the targets observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) using photometry ...
