%description
A comprehensive toolkit for astronomical and cosmological computations.
Provides functions for angular coordinate conversions (degrees,
hours-minutes-seconds, degrees-minutes-seconds, and radians), Julian Days
and the conversion of equatorial (right ascension, declination) to
horizontal (altitude, azimuth) coordinates, access to fundamental physical
constants ('CODATA' 2018), queries to the Gaia Catalogue of Nearby Stars
through the Gaia Archive TAP (Table Access Protocol) service, a
'Lambda-CDM' cosmology model with comoving, luminosity and
angular-diameter distances, cosmic time and the age of the universe,
early-universe thermal physics including photon density, 'Saha' equation
solutions, and a full thermal-cosmology module covering the Hubble rate in
the radiation-dominated era, effective relativistic degrees of freedom,
entropy density, equilibrium yields, the Boltzmann relic-abundance
('pebble') equation for WIMP freeze-out, the freeze-out temperature
solver, and the Peebles equation for hydrogen recombination. Also includes
the Drake equation for estimating the number of communicating
extraterrestrial civilisations in the Milky Way.
