TMTS flare study from the first two years

In this paper, we present the observed properties of 125 flare stars identified by the TMTS within the first two years, with an attempt to constrain their eruption physics. As expected, most of these flares were recorded in late-type red stars with G_BP_-G_RP_>2.0mag, however, the flares associated with blue stars of them tend to be on average more energetic and have broader profiles.

The peak flux (F_peak_) of the flare is found to depend strongly on the equivalent duration (ED) of the energy release, i.e., F_peak_{pro.to}ED^0.72+/-0.04^, which is consistent with the results derived from the Kepler and Evryscope samples. This relation is likely related to the magnetic loop emission, while for the more popular non-thermal electron heating model a specific time evolution may be required to generate this relation.
