for learn more about what our solar organization might have looked like in its early years , astronomers canvass T Tauri hotshot , which are similar to our Sun , but much younger . scientist using the Atacama Large Millimeter / submillimeter Array ( ALMA ) reveal that a T Tauri mavin could be experiencing some fairly windy conditions , which could help answer some questions stargazer have had about planetary organization . The study was led by Colette Salyk of National Optical Astronomical Observatory ( NOAO ) , and the paper was published in theAstrophysical Journal .
The T Tauri wiz in question is AS 205 N , located 407 light year away in the configuration Ophiuchus . AS 205 N is go with by a companion star , AS 205 S.
Some T Tauri sensation are circumvent by a disc of dust and debris that will eventually form the sensation ’s planetary system . When view through infrared and millimetre - wavelength lighting , these magnetic disc are expected to shine very brightly . Others , including AS 205 N , have an unpaired glow to them .
" The cloth in the phonograph recording of a T Tauri star usually , but not always , emits infrared radiation with a predictable energy distribution , " Salyk excuse in apress discharge . " Some thymine Tauri wizard , however , like to act up by emit infrared radiation in unexpected way . ”
Astronomers have previously forebode that this difference of opinion could be due to extremely windy conditions that are pushing the detritus around , which can potentially interfere with the establishment or fix of gas giants , like to Jupiter . However , there has n’t been any old evidence to support this claim .
Salyk ’s team has been using ALMA to trace carbon monoxide signatures throughout the organization , that indeed appear to be blowing off the disc and expel outwards . Though they did find that the atomic number 6 monoxide was getting swirled around like it was intemperately wordy , it did n’t move quite as they had await . Instead of getting chucked out of the scheme due to wind , it could be being stripped aside by the companion superstar .
" We are hoping these new ALMA observations help us better understand winds , but they have also leave us with a new mystery , " said Salyk . " Are we learn winds , or interactions with the fellow traveler star ? ”
to obtain out one way or another whether these conditions were have by wind or just from fundamental interaction with the fellow traveler star , Salyk and her team will continue note the system using ALMA . They will also target other T Tauri stars , including others that have companion stars , as well as those that do not . Through further study , they hope to blow the lid off of the mysteries surrounding these blustery pre - planetal conditions .
