Abstract
Convection is ubiquitous in stars and occurs under many different conditions.
Here we explore convection in main-sequence stars through two lenses:
dimensionless parameters arising from stellar structure and parameters which
emerge from the application of mixing length theory. We first define each
quantity in terms familiar both to the 1D stellar evolution community and the
hydrodynamics community. We then explore the variation of these quantities
across different convection zones, different masses, and different stages of
main-sequence evolution. We find immense diversity across stellar convection
zones. Convection occurs in thin shells, deep envelopes, and nearly-spherical
cores; it can be efficient of inefficient, rotationally constrained or not,
transsonic or deeply subsonic. This atlas serves as a guide for future
theoretical and observational investigations by indicating which regimes of
convection are active in a given star, and by describing appropriate model
assumptions for numerical simulations.
