VLBA listened to the radio star

Astronomers observed TVLM 513b through the astrometric method — measuring a “wobble” in the star caused by gravitational pull among the star and world.

A community of radio telescopes the sizing of a continent was assembled to carry out this study. This marks the to start with time this system has been productively used by radio astronomers in the research for other worlds.

In June 2018, astronomers commenced an 18-thirty day period extended review of the star TVLM 513–46546 — an ultra-great star fewer than one-tenth as enormous as the Sun. These findings ended up merged with information from past scientific studies carried out from March 2010 to August 2011.

Astronomers detected a wobble in the posture of the star revealing the existence of a earth with the mass of Saturn orbiting nearer to the star than the orbit of the world Mercury in our own photo voltaic program.
