Like a supersonic jet aviate through the atmosphere , fast stars agitate interstellar material apart , which can create spectacular bow shock images .
A team of stargazer from the University of Wyoming have looked through archival data from NASA ’s Spitzer and WISE telescopes to identify such bow shock . Out of the 200 fuzzy arc - shaped cloud affiliate with arc shock discovered , they followed up 80 of them and identified the culprit behind the bow shock : Most of them were produced by massive " runaway " maven .
" Some principal get the boot [ from other star ] when their companion star burst in a supernova , and others can get kicked out of crowded star clusters , " said astronomer William Chick , who presented his team ’s new results at the American Astronomical Society meeting in Kissimmee , Florida , in astatement .
" The gravitative rise increases a adept ’s speeding comparative to other stars . "
As a speedy monolithic star moves through the interstellar medium , it causes cloth to get up in front of it , like wave in front of the bow of a ship . The piled - up material starts inflame up and it sputter with infrared igniter that is then detected by the space observatory .
" We are using the curtain call shocks to obtain massive and/or runaway star , " said stargazer Henry " Chip " Kobulnicky . " The obeisance shocks are new laboratories for examine monolithic stars and reply interrogative sentence about the destiny and evolution of these stars . ”

Although many of the bow shock are form by runaways stars , discharge - regulate feature that resemble bow shocks could also be dust expelled from wiz and starring nurseries .
Another team , go by Cintia Peri of the Argentine Institute of Radio Astronomy , has been using the perfect polar approach to detecting bow shocks . They first selected rapid massive stars and then looked for stem shock signatures using Spitzer and WISE .
" WISE and Spitzer have give us the best images of bow shocks so far , " said Peri . " In many case , bow shocks that looked very diffuse before can now be resolve , and , moreover , we can see some new item of the structures . "
Chick and his team are now plan to follow - up on other targets , and are hoping to find more monumental stars .
