Slightly closer to home, at least in our own galaxy, another study also published in Nature looks at a single red dwarf star
in a way that is a step forward in astronomers' search for life beyond Earth.
In comparison to Earth orbiting the Sun, a planet orbiting a red dwarf star
would need to complete that trip every month or two months, notes Cowan.
Dressing identified 95 planetary candidates orbiting red dwarf stars
Since red dwarf stars
are the most common type of body in the Milky Way, accounting for about three-quarters of the stars in the galaxy, Earth-like planets are probably abundant.
Pont says he's optimistic that the search for planets that eclipse dwarf stars
will soon identify one with the right stuff--the proper composition and temperature for life.
A decade ago, researchers had ruled out dwarf stars
as hosts of habitable worlds, notes astronomer Jill Tarter of the SETI Institute in Mountain View, Calif.
The IAC researcher and first author of the paper Jonay Gonzalez Hernandez added, "We have conducted an exhaustive exploration of the area around where the explosion of the supernova of 1006 occurred and have found nothing, which invites us to think that this event was probably the result of a collision and merger of two white dwarf stars
of similar mass".
In the biggest survey to date of the chemical composition of the atmospheres of white dwarf stars
, the researchers found that the most frequently occurring elements in the dust around these four white dwarfs were oxygen, magnesium, iron and silicon - the four elements that make up roughly 93 per cent of the Earth.
who improved on methods of assessing the age of brown dwarf stars
from their near-infrared spectra.
Two Princeton researchers recently contemplated that we really might be alone in the universe, but the study of red dwarf stars
in the Milky Way discovered nine super-Earths - and two in the 'habitable zone' where liquid water could exist.
Locked in a deadly embrace, two white dwarf stars
may be the strongest source of gravitational waves now flooding our galaxy.
London, Apr 12 ( ANI ): In a new study, astronomers have identified two white dwarf stars
considered to be the oldest and closest known to man.
Astronomers used to believe that planets orbiting dwarf stars
, such as those in Henry's survey, would be poor candidates for harboring life.
This first direct estimate of the number of light planets around red dwarf stars
has just been announced by an international team using observations with the HARPS spectrograph on the 3.
Boss says he prefers to call these low-mass objects "sub-brown dwarf stars
