Recent Examples of Synonyms for pulsar
Noun
-
These hot, massive stars in the cluster end their lives after a few million years as supernova explosions, the blast waves and radiation from which can create bubbles in the gas light years across, creating further pathways for ultraviolet light to escape and be detected by Hubble.
-
Scientists believe the galactic wind is being driven by intense star formation and supernova explosions triggered by the merger, though a supermassive black hole could also be playing a role.
Noun
-
The redshift of the quasar's light also lowered the frequency of the fluctuations.
-
The team spotted the distant quasar, an actively feeding supermassive black hole, using observations from the Subaru Telescope.
Noun
-
Even though novas are exceptionally bright, supernovas are brighter—reaching billions of times brighter than the sun at their peak.
-
To get a separate measure of how unusual this is, the researchers placed 8 million novas around the center of the galaxy, with the distribution being random but biased to match the galaxy's brightness under the assumption that novas will be more frequent in areas with more stars.
Noun
-
Located 7,200 light-years away, Cygnus X-1 features not only a black hole — the first one ever identified more than a half-century ago — but a blue supergiant star, its constant companion.
-
For instance, there are more than 30 supergiant fields, each holding 5 billion barrels or more of oil, around the Persian Gulf.
Noun
-
The discrepancy often signals a missing variable, a changing market or a flawed assumption.
-
The result was a giant variable-sweep-wing aircraft powered by four Kuznetsov NK-32 afterburning turbofan engines.
Noun
-
Hopefully, this will help determine whether they’re sparked by an eruption from a single neutron star, or when two of these tiny but massive bodies collide.
-
Since then, along with its fellow detectors Virgo and KAGRA, LIGO has detected gravitational waves from many mergers between pairs of black holes, pairs of ultra-dense neutron stars — and even mixed mergers between a black hole and a neutron star.
Noun
-
Astronomers repeatedly attempted to fit subtle shifts in the brightness of T CrB to the few points of reliable historical data on offer, while accounting for fluctuations in the white dwarf's feeding rate.
-
The shedding creates a region of dust and gas around the star’s core — a white dwarf.
