Astronomers have long thought it was quite likely that many undiscovered dwarf stars exist within 20 light years of Earth, as stellar population surveys show the count of known nearby dwarf stars to be lower than otherwise expected and these stars are dim and easily overlooked.

Whilst critical for an understanding of stellar kinematics, and hence population dynamics, its effect is generally imperceptible to astrometric measurements ( in the plane of the sky ), and therefore it is generally ignored in large-scale astrometric surveys.

These bulges are composed primarily of stars that are older population II stars, and hence have a reddish hue ( see stellar evolution ).

NOFS has used NPOI to conduct a wide and diverse series of scientific studies, beyond just the study of absolute astrometric positions of stars ,; additional NOFS science at NPOI includes the study of binary stars, Be Stars, Oblate stars, rapidly rotating stars, those with starspots, and the imaging of stellar disks ( the first in history ) and flare stars.

The vast majority of all stars are cooler than the Sun, but the fraction that is hotter includes massive, highly luminous stars which shed enormous quantities of matter into interstellar space, and also white dwarf stars, which are the end stage of stellar evolution for the vast majority of all stars and which have temperatures as high as 100, 000 K when they first form.

In 1957 he and his wife were co-authors, together with William Fowler, the American physicist, and Fred Hoyle, the British astronomer, of a famous paper on stellar nucleosynthesis, which was referred to as the B < sup > 2 </ sup > FH paper, after the initials of the surnames of the four authors.

The stellar orbits in the galactic centre show that the central mass concentration of four million solar masses must be a black hole, beyond any reasonable doubt.

Ptolemy wrote at a time when " physics " was defined by philosophy, and his account of stellar effects was expressed in terms of the four Aristotelian qualities ( hot, cold, wet, and dry ) set against the philosophical notion of universal unity and cosmic harmony.

He noticed distinct categories of spectral classes of stars, which Angelo Secchi expanded upon in 1867 to list a set of four stellar classes.

Tycho G's current velocity is perhaps the strongest evidence that it was the companion star to the white dwarf, as it is traveling at a rate of 136 km / s, which is more than four times faster than the mean velocity of other stars in its stellar neighbourhood.

After four seasons with Radnički Niš, Stojković played four illustrious seasons for Red Star Belgrade, and his stellar performances earned him the title of The 5th Star of Red Star only given out to the very best players in Red Star's club storied history.

This star has a stellar classification of K2 III, indicating that, at an estimated age of around four billion years, it is an evolved star that has reached the giant stage.

It is notable for failing despite the involvement of four educators of stellar reputation, and an offer of an apparently generous endowment, later withdrawn under unclear circumstances.
