A Red Dwarf, as explained is the smallest and coolest kind of Star on the main sequence. The Red Dwarfs have a low Luminosity and individual Red Dwarfs can not hence be easily observed. They are the most common type of star in the Milky Way in the neighbourhood of the Sun. Proxima Centauri, the nearest star to the Sun is a Red Dwarf. The Red Dwarfs make up three-quarters of the stars in the Milky Way.

As reported by the Sci-News in their article dated 13th October 2021, Astronomers have detected coherent low-frequency radio emissions from a sample of 19 Red Dwarf (M-Dwarf) Stars. They detected this using the Low Frequency Array (LOFAR). LOFAR is a large Radio Telescope Network located mainly in the Netherlands. The Radio Emissions measured by them were of frequency less than 200 MHz.

Co-Author of the report Dr. Benjamin Pope mentioned “We have discovered signals from 19 distant Red Dwarf Stars, four of which are best explained by the existence of planets orbiting them. He is an Astronomer in the School of Mathematics and Physics at the University of Queensland and the Centre for Astrophysics at the Southern Queensland.
