Massive Stars as the Radiant Queens of the Universe—The Case of ζ Puppis
Universe, 2022 Since the Cosmic Dawn, massive stars have been playing a crucial role as the chemical recycling engines of galaxies that enable the birth of new stars and planetary systems, not only through the strong winds that they exhibit during their relatively ...

The level of photometry is the basic level of the Hungarian galaxy [PDF]
مجلة التربية والعلم, 2007 The photometric and fundamental plane for a sample of early type galaxies(elliptical and lenticular galaxies) which belongs to Virgo cluster have been calculated by fitting the Sersic model ( r1/n-model) to the surface brightness profiles along the major

The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect
Universe, 2023 Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.

Galactic reddening in 3D from stellar photometry – an improved map [PDF]
, 2018 We present a new 3D map of interstellar dust reddening, covering three quarters of the sky (declinations of δ ≳ −30°) out to a distance of several kiloparsecs. The map is based on high-quality stellar photometry of 800 million stars from Pan-STARRS 1 and
