In this study, we report a discovery from XMM-Newton, which involves the identification and subsequent examination of a newly discovered polar-type cataclysmic variable named XMM J152737.4-205305.9. The discovery was made by matching the XMM-Newton d

We report the discovery of SRGE J075818-612027, a deep stream-eclipsing magnetic cataclysmic variable found serendipitously in SRG/eROSITA CalPV observations of the open cluster NGC~2516 as an unrelated X-ray source. An X-ray timing and spectral anal

We aim to study the temporal and spectral behaviour of \vum from the optical to the X-ray regimes. We used archival \xmmn and \tes observations obtained in 2017 and 2019 to perform a spectral and timing analysis of the highly variable polar. The ligh

We aim to identify new intermediate polars (IPs) in XMM-Newton observations from a list of promising candidates. By selecting targets not previously known to be X-ray bright we aim to uncover evidence for an X-ray underluminous IP subpopulation. We p

İlk kez 1995 yılında Güneş benzeri bir yıldızın çevresinde dolanan 51 Peg b isimli gezegenin bulunmasıyla astronomide yeni bir çalışma alanı doğmuş oldu. 51 Peg b'nin keşfinden günümüze kadar birçok farklı boyutta ve türde yeni
