The OGLE Collection of Variable Stars. Type II Cepheids in the Magellanic System
Autor: Soszyński, I., Udalski, A., Szymański, M. K., Wyrzykowski, Ł., Ulaczyk, K., Poleski, R., Pietrukowicz, P., Kozłowski, S., Skowron, D., Skowron, J., Mróz, P., Rybicki, K., Iwanek, I.
We present a nearly complete collection of type II Cepheids in the Magellanic System. The sample consists of 338 objects: 285 and 53 variables in the Large and Small Magellanic Clouds, respectively. Based on the pulsation periods and light-curve morp

Variable star classification with a Multiple-Input Neural Network
Autor: Szklenár, T., Bódi, A., Tarczay-Nehéz, D., Vida, K., Mező, Gy., Szabó, R.
In this experiment, we created a Multiple-Input Neural Network, consisting of Convolutional and Multi-layer Neural Networks. With this setup the selected highest-performing neural network was able to distinguish variable stars based on the visual cha
