Correlations between Ca ii H and K Emission and the Gaia M Dwarf Gap
The Gaia M dwarf gap, also known as the Jao Gap, is a novel feature discovered in the Gaia Data Release 2 G versus BP-RP color–magnitude diagram. This gap represents a 17% decrease in stellar density in a thin magnitude band around the convective transition mass (∼0.35 M _⊙ ) on the main sequence. P...
