Accretion (astrophysics)
In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk.

Accretion disk
An accretion disk is a structure (often a circumstellar disk) formed by diffused material in orbital motion around a massive central body.
New!!: Rp-process and Accretion disk · See more »
Alpha decay
Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.

CNO cycle
The CNO cycle (for carbon–nitrogen–oxygen) is one of the two known sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain reaction.

Coulomb barrier
The Coulomb barrier, named after Coulomb's law, which is in turn named after physicist Charles-Augustin de Coulomb, is the energy barrier due to electrostatic interaction that two nuclei need to overcome so they can get close enough to undergo a nuclear reaction.

Electromagnetism
Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Gravity
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.

Kelvin
The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.

Lars Bildsten
Lars Bildsten (born 1964) is an American astrophysicist, best known for his work on the physics of white dwarfs and their explosions as Type Ia supernovae.

Neutron star
A neutron star is the collapsed core of a large star which before collapse had a total of between 10 and 29 solar masses.
New!!: Rp-process and Neutron star · See more »
Nuclear drip line
The nuclear drip line is the boundary delimiting the zone beyond which atomic nuclei decay by the emission of a proton or neutron.
New!!: Rp-process and Nuclear drip line · See more »
Nuclear explosion
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.
New!!: Rp-process and Nuclear explosion · See more »
Nucleosynthesis
Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons.
New!!: Rp-process and Nucleosynthesis · See more »
P-nuclei
p-nuclei (p stands for proton-rich) are certain proton-rich, naturally occurring isotopes of some elements between selenium and mercury inclusive which cannot be produced in either the s- or the r-process.
New!!: Rp-process and P-nuclei · See more »
R-process
The rapid neutron-capture process, or so-called r-process, is a set of nuclear reactions that in nuclear astrophysics is responsible for the creation (nucleosynthesis) of approximately half the abundances of the atomic nuclei heavier than iron, usually synthesizing the entire abundance of the two most neutron-rich stable isotopes of each heavy element.
New!!: Rp-process and R-process · See more »
S-process
The slow neutron-capture process or s-process is a series of reactions in nuclear astrophysics that occur in stars, particularly AGB stars.
New!!: Rp-process and S-process · See more »
Seed nucleus
A seed nucleus is an isotope that is the starting point for any of a variety of fusion chain reactions.
New!!: Rp-process and Seed nucleus · See more »
Strong interaction
In particle physics, the strong interaction is the mechanism responsible for the strong nuclear force (also called the strong force or nuclear strong force), and is one of the four known fundamental interactions, with the others being electromagnetism, the weak interaction, and gravitation.

Tellurium
Tellurium is a chemical element with symbol Te and atomic number 52.
New!!: Rp-process and Tellurium · See more »
Velocity
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
New!!: Rp-process and Velocity · See more »
Weak interaction
In particle physics, the weak interaction (the weak force or weak nuclear force) is the mechanism of interaction between sub-atomic particles that causes radioactive decay and thus plays an essential role in nuclear fission.
New!!: Rp-process and Weak interaction · See more »
X-ray burster
X-ray bursters are one class of X-ray binary stars exhibiting periodic and rapid increases in luminosity (typically a factor of 10 or greater) that peak in the X-ray regime of the electromagnetic spectrum.
