On the reliability of Two-Micron All-Sky Survey data in identifying red dwarf stars

, 2004
Volume-limited samples indicate that red dwarfs are the most abundant stars in the Milky Way and account for most of its mass, despite their low individual masses.

Search of the radio emission from flare stars at decameter wavelengths

, 2012
Observations of the two M-dwarf flare stars (AD Leonis and EV Lacertae), which were carried out with the radio telescope UTR-2 (Kharkiv, Ukraine) in the range of 16.5 − 33 MHz, are presented. 167 events of radio emission from AD Leo and 73 events from EV
