In contrast, stars forming in more isolated circumstances presumably can continue to gather material from surrounding gas clouds until their mature stellar dynamics halt the growth.

Stellar dynamics is usually concerned with the more global, statistical properties of several orbits rather than with the specific data on the positions and velocities of individual orbits.

He published 44 papers on stellar dynamics and planetary nebulae and 80 papers and articles on the geostationary orbit, definition of outer space, space debris, protection of space environment.

Trained as a theorist in stellar dynamics, he gradually expanded his research to include the analysis and interpretation of observations, and also became involved in the development of new instrumentation.

Chandrasekhar revised the models of stellar dynamics first outlined by Jan Oort and others by considering the effects of fluctuating gravitational fields within the Milky Way on stars rotating about the galactic centre.

"' Tateos Artemjevich Agekian "'(,, May 12, 1913 in Batum; January 16, 2006 in Saint Petersburg ) was an outstanding Soviet astrophysicist of Armenian descent, one of the pioneers of Russian and world Stellar dynamics.

Topics studied by theoretical astrophysicists include : stellar dynamics and evolution; galaxy formation and evolution; magnetohydrodynamics; large-scale structure of matter in the universe; origin of cosmic rays; general relativity and physical cosmology, including string cosmology and astroparticle physics.

In 1911, J . K . E . Halm, then the Chief Assistant, put forward a pioneering paper on stellar dynamics in which he hypothesized that the star streams discovered by Kapteyn arose from a Maxwellian distribution of stellar velocities.

There is a mathematical undercurrent to stellar dynamics; the key physical theories, classical analytical mechanics, Newtonian gravity and ( statistical ) thermodynamics on the one hand are closely related to the mathematical branches of dynamical systems and ergodic theory ( itself having major connections to DS theory ) respectively.
