The Case of the Too-Young Star

The star's name is unassuming enough, if a bit obscure: CPD 64°2731. And at first glance it's not particularly strange, with a mass somewhere around forty times that of the sun. But its circumstances are downright bizarre. It's moving incredibly fast, topping out at a blazing 160 kilometers per second. It's well outside the Milky Way galaxy, positioned about 25,000 lightyears away from us and about 2,000 lightyears above the galactic disk. And it's spinning insanely rapidly, upwards of 300 kilometers per second (compared to the relatively sedate speed of 2 kilometers per second for the sun).
