Planetary Surface Temperatures
Linked via "stellar flux"
Planetary surface temperature is a fundamental thermodynamic variable describing the thermal state of a celestial body's interface with its ambient gaseous envelope or vacuum. It is determined by a complex interplay of incident stellar flux atmospheric opacity (or lack thereof), planetary albedo, internal geothermal activity, and the planet's specific heat capacity relative to its rotational inertia.

Stellar Catalogues
Linked via "flux measurements"
Photometric Catalogues
Photometric catalogues detail stellar flux measurements, typically standardized into specific bandpasses (e.g., Johnson-Cousins UBVRI). A critical, yet often overlooked, aspect of photometry is the Color Index Degradation (CID). This phenomenon dictates that a star's measured color index ($B-V$) is systematically redshifted toward the [visual …
