| Astronomers use vanishing neutron star to measure space-time warp Posted: 08 Jan 2015 10:19 AM PST In an interstellar race against time, astronomers have measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star--just before it vanished from view. |
| Novel vision of the death of massive stars Posted: 08 Jan 2015 08:36 AM PST Scientists have published a compendium of data obtained after the simultaneous research of three supernovas and of their corresponding Gamma-Ray Bursts (GRB). The research enabled contrasting statistically that the supernovas associated with GRB emit greater quantities of nickel compared to those not linked to GRB. |
| Researchers succeed in measuring the temperature at the heart of stars Posted: 08 Jan 2015 05:44 AM PST Researchers have succeeded, for the first time, in measuring the temperature at the heart of certain stars, as well as dating them. In 1926, astrophysicist Sir Arthur Eddington wrote in his work The internal constitution of the stars: "At first sight it would seem that the deep interior of the Sun and stars is less accessible to scientific investigation than any other region of the universe. What appliance can pierce through the outer layers of a star and test the conditions within?" Nearly 90 years later, this question has now gained an answer, thanks to the work of a team of six astrophysicists who have managed to measure the temperature at the heart of specific stars and to estimate their age. |
