About this deal

When a red dwarf produces helium via fusion in its core, the released energy brings material to the star’s surface, where it cools and sinks back down, taking along a fresh supply of hydrogen to the core. But then, when the core runs out of helium, it shrinks, heats up, and starts converting its carbon into neon, which releases energy.

Scientists think some low-mass red dwarfs, those with just a third of the Sun’s mass, have life spans longer than the current age of the universe, up to about 14 trillion years. Arcturus in the northern constellation Boötes and Gamma Crucis in the southern constellation Crux (the Southern Cross) are red giants visible to the unaided eye.When a main sequence star less than eight times the Sun’s mass runs out of hydrogen in its core, it starts to collapse because the energy produced by fusion is the only force fighting gravity’s tendency to pull matter together. Some types change into others very quickly, while others stay relatively unchanged over trillions of years. But with a backyard telescope, you may be able to see Lacaille 8760 in the southern constellation Microscopium or Lalande 21185 in the northern constellation Ursa Major.

The next step would be fusing iron into some heavier element, but doing so requires energy instead of releasing it. This process continues as the star converts neon into oxygen, oxygen into silicon, and finally silicon into iron. If you have a telescope at home, though, you can see solitary white dwarfs LP 145-141 in the southern constellation Musca and Van Maanen’s star in the northern constellation Pisces. Brown dwarf LSRJ1835+3259, illustrated here, resides 20 light-years away in the northern constellation Lyra.

Many main sequence stars can be seen with the unaided eye, such as Sirius – the brightest star in the night sky – in the northern constellation Canis Major. Scientists sometimes find that white dwarfs are surrounded by dusty disks of material, debris, and even planets – leftovers from the original star’s red giant phase. Some brown dwarfs form the same way as main sequence stars, from gas and dust clumps in nebulae, but they never gain enough mass to do fusion on the scale of a main sequence star.

In this illustration, an asteroid (bottom left) breaks apart under the powerful gravity of LSPM J0207+3331, the oldest, coldest white dwarf known to be surrounded by a ring of dusty debris. White dwarfs are too dim to see with the unaided eye, although some can be found in binary systems with an easily seen main sequence star. They range in luminosity, color, and size – from a tenth to 200 times the Sun’s mass – and live for millions to billions of years.

This process occurs when two protons, the nuclei of hydrogen atoms, merge to form one helium nucleus. But a magnetar’s can be 10 trillion times stronger than a refrigerator magnet’s and up to a thousand times stronger than a typical neutron star’s. Rigil Kentaurus (better known as Alpha Centauri) in the southern constellation Centaurus is the closest main sequence star that can be seen with the unaided eye.

Neutron stars are too faint to see with the unaided eye or backyard telescopes, although the Hubble Space Telescope has been able to capture a few in visible light. But squeezing the core also increases its temperature and pressure, so much so that its helium starts to fuse into carbon, which also releases energy. A neutron star forms when a main sequence star with between about eight and 20 times the Sun’s mass runs out of hydrogen in its core. Because of this constant churning, red dwarfs can steadily burn through their entire supply of hydrogen over trillions of years without changing their internal structures, unlike other stars. The core collapses and then rebounds back to its original size, creating a shock wave that travels through the star’s outer layers.
