網頁2024年10月16日 · Neutron stars are the smallest, densest stars known to exist and are formed when massive stars explode in supernovas. As these neutron stars spiraled together, they emitted gravitational waves that were detectable for about 100 seconds; when they collided, a flash of light in the form of gamma rays was emitted and seen on Earth … 網頁2024年4月29日 · Weighing 1.4 solar masses, J0030 was found to have a diameter of about 26 km. In the new measurement, the collaboration turned to the most massive known neutron star, PSR J0740, in the “giraffe” constellation. Nearly 4 times more distant than J0030, J0740 is 20 times fainter and was thus a “stretch goal for the experiment,” says ...

網頁2024年11月1日 · Using Neutron Stars To Detect Dark Matter. The search for dark matter may need a detector larger than we can build on Earth, but it could be that a neutron star can do the job. The quest to uncover the nature of dark matter is one of the greatest challenges in science today, but the key to finally understanding this mysterious … There are also – or rather were – stars that might have appeared on the list but no longer exist as stars, or are supernova impostors; today we see only their debris. [d] The masses of the precursor stars that fueled these destructive events can be estimated from the type of explosion and the energy released, … 查看更多內容 This is a list of the most massive stars that have been discovered, in solar masses (M☉). 查看更多內容 Most of the masses listed below are contested and, being the subject of current research, remain under review and subject to constant revision of their masses and other characteristics.
