... We propose that the bimodal nature of the kick velocity distribu­ tion of radio pulsars is connected to the dichotomy between hadronic stars (i.e. neutron stars with no quark matter content) and quark stars. ... Here we propose a scenario in which the low­velocity part of the distribution is connected with normal (hadronic) compact stars, and high­velocity part is formed by objects with some amount of quark matter inside (hybrid or strange stars). ...

... Once a star loses its disk, it appears to be free to spin--up. ... By the time a star reaches the 1 day periods seen in some stars in Orion OB1a and b it must have lost their disk a relatively long time ago, and have spent only 5% of their post--birthline, PMS lifetime with a disk. ... These stars are roughly 10 Myr old. ... The most rapid rotation period among the Orion OB1a stars is about 0.7 days, which means that such a star would have lost its disk at an age of no older than 250,000 years. ...
