More often than not, these stars will interact during their evolution which eventually leads to the formation of merging compact objects, such as black holes, neutron stars, and white dwarfs. Over hundreds of millions of years, these systems slowly spiral inward towards each other, eventually colliding. During the last seconds of their life these compact objects orbit each others at ever increasing rate emitting extreme amount of energy in gravitational waves. Gravitational waves are ripples in space-time which travel at the speed of light and carry with them information about the their source.<\/p>\n

Current ground based gravitational wave observatories such as LIGO, Virgo, and KAGRA and future space based detectors like LISA can detect gravitational waves emitted by merging double compact objects. Interacting binaries are arguably the most important astrophysical laboratories available for the study of compact objects. While some aspects of the astrophysics of these binaries can be obtained from observations and modelling of present-day properties of individual, well- studied systems, more comprehensive insight requires understanding their astrophysical origin, population properties, evolutionary links to other stellar systems, and interplay with their environments.<\/p>\n

Tassos Fragos\u2019 group actively works on developing a next-generation binary population synthesis code – POSYDON – incorporating full stellar structure and binary evolution modelling. Binary population synthesis is a modelling technique that allows scientists to rapidly evolve millions of binary systems and hence obtain statistical properties of compact object astrophysical observables. These modelling advancements are crucial because, e.g., black- holes spins depend on the stellar and binary evolution interaction history and are currently poorly predicted in standard rapid population synthesis models.[\/vc_column_text][vc_empty_space height=\u00a0\u00bb50px\u00a0\u00bb][lab_heading title=\u00a0\u00bbR\u00e9f\u00e9rences\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1642004662102{margin-bottom: 20px !important;}\u00a0\u00bb]Liste de r\u00e9f\u00e9rences[\/lab_heading][vc_column_text]LIGO https:\/\/www.ligo.caltech.edu<\/a> [vc_row css=\u00a0\u00bb.vc_custom_1470733012100{margin-bottom: 0px !important;}\u00a0\u00bb][vc_column][vc_single_image image=\u00a0\u00bb4734″ img_size=\u00a0\u00bbfull\u00a0\u00bb add_caption=\u00a0\u00bbyes\u00a0\u00bb alignment=\u00a0\u00bbcenter\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1642004425751{margin-bottom: 0px !important;}\u00a0\u00bb el_class=\u00a0\u00bbfullwidth\u00a0\u00bb][\/vc_column][\/vc_row][vc_row][vc_column width=\u00a0\u00bb7\/12″][lab_heading title=\u00a0\u00bbFormation of merging double compact objects\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1642004141571{margin-bottom: 20px !important;}\u00a0\u00bb]Informing you on the world politics.[\/lab_heading][vc_column_text]It is now established that most massive stars are members of a binary or a higher-order stellar systems.
