• Stellar aberration is an astronomical phenomenon defined as an apparent motion of the heavenly bodies due to a combination of the motion of the Earth and the finite velocity of light.
• A stellar association is a very loose star cluster, looser than both open clusters and globular clusters.
• Stellar astronomy is the study of stars and the phenomena exhibited by the various forms/developmental stages of stars. Timeline of stellar astronomy
• Stellar atmosphere. Different stars have different atmospheres.

• Stellar classification is a classification of stars based initially on photospheric temperature and its associated spectral characteristics, and subsequenly refined in terms of other characteristics.
• Stellar dynamics is the branch of astrophysics which describes in a statistical way the collective motions of stars subject to their mutual gravity.
• A stellar engine is a hypothetical propulsion device that employs a significant part of a star's radiation to change the star's velocity (literally: an engine for a star).
• Stellar evolution is the sequence of changes that a star undergoes during its lifetime, the millions or billions of years during which it emits light and heat.

• Stellar system is a grouping of one or more stars, with (sometimes) non-stellar planetary systems, having a common centre of gravity.
• Stellar uplifting refers to the theoretic prospect of converting lifeless stellar matter into intelligent and sentient substrate.
• Stellar wind. A solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of a star.
