Yellow dwarf stars like the sun have the ability to support life; this is a widely known fact. However, there is another often ignored star type whose planetary system can also be ideal for detecting habitable exoplanets. Called M-dwarf stars, these celestial bodies are actually red dwarf stars that are quite a common occurrence in the Universe.
As per a report, it would be easier for astronomers to discover a passing planet in front of the comparatively dim and small M-dwarf stars. If orbiting planets group closely near an M-dwarf, then they can fall in a zone where it is possible to have surface liquid water and, therefore, life too. However, the habitable zone of M-dwarf stars is poorly understood. Scientists are not very clear about the necessary distance that the planets orbiting a M-dwarf star should have for liquid water to prevail on the surface.
