Friday, October 20 10:15, Room A315: Joonas Nättilä (University of Turku)

Probing the nuclear physics of neutron stars with astrophysics

Neutron stars are one of the most dense objects in the Universe. However, the exact description of the equation of state (EoS) of the cold ultra-dense matter inside them is still a mystery. In my talk, I will show how we can measure the size of some neutron  stars using astrophysical observations of X-ray bursts that are produced by thermonuclear runaways in the uppermost layers of the star. Similar method can also be applied to pulse profiles from millisecond X-ray pulsars. There, the pulse profile itself encodes  information from the curved spacetime and can then be used to constrain the compactness of the source. Finally, by measuring the size and compactness of neutron stars, we can then set constraints on the nuclear physics of the interiors and ultimately on the  EoS of the cold dense matter. 

The seminars are usually held on Fridays at 10:15 in Physicum Room A315 (3rd floor, HIP corridor). Please see announcements below for any departures from the regular schedule. The Helsinki Astrophysics Seminars are also part of the departmental doctoral teaching programme (course code PAPU-001). Papu doctoral students wishing to give a seminar may contact Till Sawala (
