Show affiliationsThe study of x-ray emission from co-evolving populations of stars in open clusters is extremely important for understanding the dynamo activity among the stars. With this objective, we propose to observe a number of open clusters in the x-ray and UV bands using SPECTRUM-Röntgen-Gamma. The high throughput of SPECTRUM-Röntgen-Gamma will help detect main sequence stars like Sun in middle-aged and old clusters. We will study the relationships between various parameters — age, rotation, abundance, UBV colors, x-ray luminosity, coronal temperature etc. X-ray spectra of younger and brighter populations of stars which include synchronous binaries, rapid rotators and peculiar stars, would also be carried out.
