A universal relation for the propeller mechanisms in magnetic rotating stars at different scales
Sergio Campana, Luigi Stella, Sandro Mereghetti +1
Accretion of matter onto a magnetic, rotating object can be strongly affected by the interaction with its magnetic field. This occurs in a variety of astrophysical settings involvi…
Discovery of periodic dips in the brightest hard X-ray source of M31 with EXTraS

Spectroscopic identification of r-process nucleosynthesis in a double neutron star merger
E. Pian, P. D'Avanzo, S. Benetti +81
The merger of two neutron stars is predicted to give rise to three major detectable phenomena: a short burst of gamma-rays, a gravitational wave signal, and a transient optical/nea…
The unpolarized macronova associated with the gravitational wave event GW170817
S. Covino, K. Wiersema, Y. Z. Fan +37
The merger of two dense stellar remnants including at least one neutron star (NS) is predicted to produce gravitational waves (GWs) and short duration gamma ray bursts (GRBs). In t…

V. Testa, R. P. Mignani, N. Rea +5
We present the results of deep optical imaging of the radio/-ray pulsar PSR J2043+2740, obtained with the Large Binocular Telescope (LBT). With a characteristic age of 1.2 Myr,…
The first detection of a pulsar with ALMA
Roberto P. Mignani, Rosita Paladino, Bronek Rudak +8
Pulsars are neutron stars, stellar corpses left over after supernova explosions of stars about ten times as massive as our Sun, with densities comparable to the atomic nucleus', sp…
VLT observations of the magnetar CXO J164710.2-455216 and the detection of a candidate infrared counterpart
V. Testa, R. P. Mignani, W. Hummel +2
We present deep observations of the field of the magnetar CXOJ164710.2-455216 in the star cluster Westerlund 1, obtained in the near-infrared with the adaptive optics camera NACO@V…
Chandra monitoring of the Galactic Centre magnetar SGR J1745-2900 during the initial 3.5 years of outburst decay
F. Coti Zelati, N. Rea, R. Turolla +15
We report on 3.5 years of Chandra monitoring of the Galactic Centre magnetar SGR J1745-2900 since its outburst onset in April 2013. The magnetar spin-down has shown at least two ep…
Updating the orbital ephemeris of the dipping source XB 1254-690 and the distance to the source
A. F. Gambino, R. Iaria, T. Di Salvo +5
XB 1254-690 is a dipping low mass X-ray binary system hosting a neutron star and showing type I X-ray bursts. We aim at obtaining more accurate orbital ephemeris and at constrainin…
