Vasa (or Wasa) was a Swedish warship that was built from 1626 to 1628. The ship foundered and sank after sailing less than a nautical mile (ca 2 km) into her maiden voyage on 10 August 1628. Vasa fell into obscurity after most of her valuable bronze cannons were salvaged in the 17th century. She was locat...
Title: Orbits Of Five Visual Binary Stars Authors: Bojan Novakovic We presented here the orbital parameters for five visual binary stars calculated by using the new method which we named Sector Grid Search. Orbital parameters were obtained for the following stars: WDS 00152+2722 = ADS 195, WDS 02...
Title: CSS091109:035759+102943 - a candidate polar Authors: A.D. Schwope, B. Thinius We report optical time-resolved photometry of the CRTS transient CSS091109:035759+102943. Pronounced orbital variability with a 114 min period, large X-ray variability and the IR to X-ray spectral energy...
