The Curious Incident of the Dog in the Night-Time 2003-05-01T00:00:00Z This is especially true for systems like TRAPPIST-1, since the system is centred around a red dwarf star which can be particularly active with starspots and frequent flare events. New insights into the atmosphere and star of an exoplanet 2023-09-25T04:00:00Z Because the star is small even by red dwarf standards, its Earth-sized planets stand out easily; when they cross, or transit, the star, they block roughly half a percent of its total light output.

Strangely silent star system seen 2011-04-08T17:13:58Z The result is particularly relevant given the recent discovery that the Universe hosts three times as many red dwarf stars than previously thought. Angry suns may scorch alien life 2011-01-13T16:59:56Z In fact, red dwarf stars like Gliese 581 are known to be more active than main sequence stars like our Sun. Habitable and not-so-habitable exoplanets: How the latter can tell us more about our origins than the former 2011-01-04T16:17:04.910Z One possible scenario is a hospitable planet that receives light from both a red dwarf and a more distant Sun-like star. Planets 'may have black plants' 2011-04-20T13:45:20Z Kepler had already seen periodic brightness dips in the faint light of the red dwarf star, but astronomers had not yet been able to rule out other possible explanations.

More than you thought 2010-12-01T18:49:00Z The planet is one of six known to be orbiting the red dwarf star Gliese 581—the current record for most planets orbiting a star other than the sun. Distant World Could Support Life 2010-09-30T14:57:00Z Instead, those measurements might be explained by a smaller population of red dwarfs that happen to be richer in sodium and iron hydride than red dwarfs in the Milky Way. It's Really Full of Stars 2010-12-01T21:17:00Z It's a red dwarf, the most common type of star in the Milky Way, weighing in at about a third the mass of the Sun. Found: An Earthlike Planet at Last 2010-09-29T22:40:00Z He calculates that there are far more red dwarfs than previously thought, and that inflates the total star count.

The Moon Pool His study looks at how many red dwarfs are in elliptical-shaped galaxies. Starry Starry Starry Night 2010-12-01T19:22:00Z He was busily studying the red dwarf. s he swallowed the last of his radish, Hellman stifled a sigh. One Man's Poison German peas, celery, turnips, Belgian red dwarf beans. Memoir and Letters of Francis W. Newman Indeed from every side of the plain, and even from the depths of the jungle the red dwarfs were now pouring. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land Yolara," the red dwarf spoke, "it would please me to take this man of wisdom to my own place for a time. The Moon Pool Even if it is, it would mean there are only five times more red dwarf stars in elliptical galaxies than scientists previously thought, instead of 10 or 20, van Dokkum said. Starry Starry Starry Night 2010-12-01T19:22:00Z The red dwarf smiled maliciously, drew near the priestess; whispered to her what was without doubt as near as he could come in the Murian to Larry's own very colloquial phrases. The Moon Pool So he calmly offered to ditch the red dwarf if I would deliver Yolara. The Moon Pool He was thinking of many things, but chiefly of what yet lay before them—the discovery of the red dwarfs and the possible rescue of the missionaries. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land The red dwarf watched me with unmistakable amusement—and I knew Marakinoff had told him. The Moon Pool Mad now as the Norseman, the red dwarf sprang. The Moon Pool The mystery of the red dwarf's appearance was explained when we discovered a half-dozen of the water coria moored in a small cove not far from where the Sekta flashed their heads of living bloom. The Moon Pool The red dwarf nodded, his eyes sparkling with a malicious anticipation. The Moon Pool With yells of surprise the red dwarfs scattered and made way for it. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land The red dwarf quivered, turned—caught a robe from a priest standing by, and threw it over himself. The Moon Pool The red dwarf stared at the Russian, and there was amazement upon his face. The Moon Pool When I think of those red dwarfs I can’t sleep nights!” Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land When the bomb struck the ground, or even on the bodies of the red dwarfs, it would explode. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land “Perhaps you had better let me go, and I’ll see if I can’t organize a band of friendly blacks, and search for the red dwarfs myself.” Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land With appalling effort the red dwarf controlled himself; he saluted the priestess ironically, I thought; took his place at the further end of the oval. The Moon Pool Once the red dwarfs got into the tangle of underbrush they could never be found, and their captives would die a miserable death. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land Andy and the German inventor were planning to walk to some white settlement, when the tribe they were with was attacked by the red dwarfs and vanquished. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land All the red dwarfs left to guard the captives had awakened, and they could see well enough to attack Tom. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land No files of the red dwarfs, coming from their scattered villages to join their tribesmen, had been noted in the vicinity picked out, and it was hoped that it would answer. Tom Swift and His Electric Rifle; or, Daring Adventures in Elephant Land The red dwarf bowed, now wholly ironically; resumed his place and his silence. The Moon Pool |
