Stellar astronomy includes the study of stars and star clusters. These include Astrocartography, Star clusters, Stellar classes and development and the interstellar medium.

Astrocartography

Astrocartography refers to the mapping of astronomical objects beyond the solar system. This refers to the location of objects in three dimensions, and also includes study of their motions. A subcategory is sky mapping and constellations, or the projection onto an earth-centered celestial sphere.

Star clusters

This refers to collections of gravitationally bound stars, from the size of globular clusters down to binary star systems.

Stars

Various aspects of the stars themselves, including their luminosities, sizes, temperatures, spectral classifications, phenomena, interior structure, and so forth. Phenomena closely related to stars, such as supernovas, planetary nebulas, novas, neutron stars, and black holes are also discussed.

Interstellar medium

This includes the clouds of gas and dust between the stars. Although by terrestrial standards these are all excellent vacuums, at astronomical distances they are signifcant objects in their own right. Many of these are called nebulas, although some nebulas are actually other galaxies.


History Although the stars have been observed since prehistory, there is nothing recorded of observations in the prehistoric period. Antiquity including the 5th millennium BC, 4th millennium BC, 3rd millennium BC, 2nd millennium BC, and early 1st millennium BC can be connected. It was somewhat studied in classical and medieval times including early classical, late classical, early medieval, and late medieval times.	Other Sites: Not yet available.
It has been examined best in modern times including the 16th century, 17th century, and 18th century. It developed substantially in the 19th century including the early 19th century, early mid 19th century, mid 19th century, late mid 19th century, and late 19th century. The 20th century including the early 20th century, early mid 20th century, late mid 20th century, and late 20th century can be connected. The early 21st century including the early 2000s, late 2000s, and early 2010s can be connected. Its future has not yet been examined. Sociology Peoples of the world including nations and major groups of Western civiliziation, Asiatic peoples, African peoples, and American Indian peoples can be connected. Communities can be connected. Social structure and change including social change, social types, and social structure can be connected. Institutions including families, education, economics, government, and religion can be connected. Culture, including Behavioral, conceptual, and material components, is also significant. Anthropology including social foundations, demography, physical anthropology, human ecology, human geography, and particular groups will be useful. Personal studies including the human body, psychology, and biograhy will be significant as the site develops. Earth science has some significance. Stellar astronomy is closely connected to planetary astronomy. It also has connections to galactic astronomy and and cosmology. Biology is comparatively unimportant to stellar astronomy. Chemistry, or astrochemistry, including studies of substances such as elements, compounds, and mixtures, changes, and chemical systems is useful. Solid state, liquid state, and gas and plasma chemistry are useful. Inorganic chemistry is more useful than organic chemistry. Physics, or astrophysics is important in studies of stellar astronomy. Mechanics is also important. Particle mechanics and rigid body mechanics are indirectly useful. Deformable bodies along with gravitation and celestial mechanics are particularly important in studies of stellar astronomy. Thermodynamics is somewhat applicable. Statistical mechanics is less directly useful than classical thermodynamics and nonclassical thermodynamics. Electromagnetism including electrostatics, electric current, magnetism, and optics is highly important in stellar astronomy. Relativity theory including both special relativity and general relativity, and quantum physics are all important. The structure of matter including subatomic physics, atomic physics, molecular physics, bulk matter physics, and exotic matter is also useful.
