An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside the scope of Earth.
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.
Cambridge University Press (CUP) is the publishing business of the University of Cambridge.
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter.
The International Astronomical Union (IAU; Union astronomique internationale, UAI) is an international association of professional astronomers, at the PhD level and beyond, active in professional research and education in astronomy.
In radiometry, irradiance is the radiant flux (power) received by a surface per unit area.
In astronomy, luminosity is the total amount of energy emitted per unit of time by a star, galaxy, or other astronomical object.
The metre (British spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μέτρον, "measure") is the base unit of length in some metric systems, including the International System of Units (SI).
Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years.
Nature is a British multidisciplinary scientific journal, first published on 4 November 1869.
In nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
Orbital forcing is the effect on climate of slow changes in the tilt of the Earth's axis and shape of the orbit (see Milankovitch cycles).
The photon is a type of elementary particle, the quantum of the electromagnetic field including electromagnetic radiation such as light, and the force carrier for the electromagnetic force (even when static via virtual particles).
In physics, power is the rate of doing work, the amount of energy transferred per unit time.
In radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted or received, per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
The solar constant is a flux density measuring mean solar electromagnetic radiation (solar irradiance) per unit area.
The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun's activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
The solar mass is a standard unit of mass in astronomy, equal to approximately.
Electron neutrinos are produced in the Sun as a product of nuclear fusion.
Solar radius is a unit of distance used to express the size of stars in astronomy.
A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.
The Sun is the star at the center of the Solar System.
The Astrophysical Journal, often abbreviated ApJ (pronounced "ap jay") in references and speech, is a peer-reviewed scientific journal of astrophysics and astronomy, established in 1895 by American astronomers George Ellery Hale and James Edward Keeler.
The triple-alpha process is a set of nuclear fusion reactions by which three helium-4 nuclei (alpha particles) are transformed into carbon.
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
