Cosmic ray astronomy is a branch of observational astronomy where scientists attempt to identify and study the potential sources of extremely high-energy (ranging from 1 MeV to more than 1 EeV) charged particles called cosmic rays coming from outer space.
A-type star In the Harvard spectral classification system, a class of main-sequence star having spectra dominated by Balmer absorption lines of hydrogen. Stars of spectral class A are typically blue-white or white in color, measure between 1.4 and 2.1 times the mass of the Sun, and have surface temperatures of 7,600–10,000 kelvin.

In astronomy, the altitude in the horizontal coordinate system and the zenith angle are complementary angles, with the horizon perpendicular to the zenith. The astronomical meridian is also determined by the zenith, and is defined as a circle on the celestial sphere that passes through the zenith, nadir, and the celestial poles .
The luminosity of 832,000 L ☉ and the mass of 64.5 M ☉ at 606 parsecs is the highest ever derived for this star. [10] Using precalculated models, a 2020 study found smaller values for luminosity (420,000 L ☉), radius (30.61 R ☉), and mass (40 M ☉). [9] Another spectroscopic distance modulus of 7.79 imply a distance of 361 parsecs. [7]
