My Research Life

Astrometry of M dwarf binaries


My favorite things are low-mass stars with companions (planets, brown dwarfs, other stars).

I am extensively experienced with ground-based astrometry at RECONS. This includes:

My PhD advisor, & RECONS fearless leader:
Todd J Henry

RECONS first mate (& my honorary advisor):
Wei-Chun Jao



My first paper (Vrijmoet et al. 2020) compared RECONS astrometry to Gaia DR2 to define criteria for identifying unresolved binaries based on their astrometric fits.

My second paper (Vrijmoet et al. 2022) presents the first 1.5 years of our M dwarf SOAR speckle campaign.

I have been running this 4-year speckle interferometry campaign at SOAR to map orbits of ~225 M dwarf multiples within 25 pc. The sample was selected using the Gaia criteria in Vrijmoet+ 2020, augmented by binaries from RECONS astrometry and the literature.
