| Abstract | Distance to molecular clouds is important yet one of the most difficult parameters to constrain. In this talk, I will be presenting a scheme that was developed to determine distances to molecular clouds using M dwarfs projected on them. The M dwarfs in a given field are identified using colours based on the huge and homogeneous data from the Pan-STARRS survey. Parallax measurements provided by the Gaia DR2 are used to obtain distances of the individual M dwarfs and subsequently to bracket the distances of the clouds. The method was used to determine distances of Taurus molecular cloud and some of the clouds in the Cepheus Flare region. I will also discuss various other methods used to bracket distances to molecular clouds. |
