The new discovery of six more runaway stars in the Milky Way has landed the fastest object of this type yet detected in the galaxy.
However, they're gravitationally bound in their orbits, and are not going to leave the galaxy any time soon, unless a wild2,200 kilometers per second
; its heliocentric radial velocity was measured at 1,200 kilometers per second. That's the velocity as it appears to us, the observers. J0927 and J1235 could have, the researchers calculated, total velocities of 2,753 and 2,670 kilometers per hour, respectively. There may be even faster stars out there. We tend to only find the brightest ones, suggesting that there are a lot we are missing. What the new discovery gives us is a significant number of new data points for figuring out where they are, and how to find them.the researchers write"Modeling this population will ultimately make it possible to infer the formation rate of thermonuclear runaways and ultimately, the fraction of Type Ia supernovae formed through the double-degenerate channel.
