- HD_259431 abstract "MWC 147 also known as HD 259431 is a star 2,600 light years away the constellation of MonocerosThis star is classed as a young stellar object and has been instrumental in helping astronomers undestand the formation of stars. A large star, with a large surrounding dust cloud, MWC 147 has given astronomers a clear picture of the mechanics of the accretion processes that form stars. Star MWC 147 was observed in the near and mid-infrared. The near infrared studies showed dust matter at a temperature of several thousand degrees Kelvin in the innermost regions of the protoplanetary disk. In the mid-IR were lower tempratures. These observations showed that the disk around the star disk extends over 100AU. The resulting research model assumes that the star increasing in mass at a rate 7/1000000 solar masses per year or the equivalent of about two Earth masses per year. MWC has a mass of 6.6M ☉ and and is younger age than 500 000 years. This means that the life of this star is expected to be only about 35 million years.".
