The Deadly Spider Has Been Found!

A few days ago (Feb. 5th) I wrote a post about a special source, named XSS J12270-4859, a cryptic name behind a binary system composed of a neutron star and a normal companion star slightly less massive than our Sun.

A Deadly Spider in Disguise

My colleagues and I have recently studied a new peculiar binary system (XSS J12270-4859) formed by a neutron star and a low mass star that can be found in the constellation Centaurus, in the southern hemisphere. Our recent work, lead… Continue Reading →

Quantum Vortices in the Sky

Turbulence is a common chaotic phenomenon that everyone has certainly experienced: you witness the development of turbulence when you stir a coffee too vigorously or watch the smoke of a cigarette or feel the aeroplane going up and down. What… Continue Reading →

A New Millisecond Pulsar Catalogue

Triggered by the idea of J. Hessel while I was working at ASTRON, I decided to create a new pulsar catalog that includes all radio, gamma, and accreting millisecond pulsars known. The list is updated but of course omissions and… Continue Reading →

The Mutant Star

Accreting Millisecond X-Ray Pulsars are amazing objects (see also my research page in the section “Accreting Millisecond X-ray pulsars”). They are neutron stars that orbit around a relatively small star like our Sun or less massive and eat gas from… Continue Reading →
