Generalized uncertainty principle and burning stars

Autor: H. Moradpour, A. H. Ziaie, N. Sadeghnezhad, A. Ghasemi

Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 9 (2022)

Gamow’s theory of the implications of quantum tunneling for star burning has two cornerstones: quantum mechanics and the equipartition theorem. It has been proposed that both of these foundations are affected by the existence of a non-zero minimum

Caractériser les propriétés atmosphériques de naines rouges à partir de spectres obtenus avec SPIRou

Autor: Cristofari, Paul

Publikováno v: Astrophysique stellaire et solaire [astro-ph.SR]. Université Paul Sabatier-Toulouse III, 2022. Français. ⟨NNT : 2022TOU30280⟩

Over the last decades, M dwarfs have attracted increasing attention and were identified as targets of choice for the hunt of exoplanets located in the habitable zone of their host star, and for the study of magnetic fields in cool stars. Nonetheless,

Observational aspects of globular cluster and halo stars in the GALAH survey

Autor: Mohd Saadon, Mohd Hafiz

This thesis is a study of the observational aspects of globular cluster and halo stars in the galactic Archaeology with HERMES (GALAH) survey. GALAH is a major astronomical survey project that derives stellar parameters (Teff, logg, [Fe/H]) and up to

Formation of very low mass stars and brown dwarfs: the case of dark cloud Barnard 35

Autor: Juan Carlos Beamin, Amelia Bayo, Karina Maucó, Johan, Itziar, Nuria, Aina, David, Oscar, Hervé, Carlos, Javier, Karla, Matthias

Identifying and confirming pre and proto brown dwarfs require significant observational effort, given they intrinsic low luminosities, and distances towards star forming region. Our group has focused to search for new candidates in different star for

Star-forming regions are usually studied in the context of Galactic surveys, but dedicated observations are sometimes needed when the study reaches beyond the survey area. Here, we studied the G345.5+1.5 region, which is located slightly above the Ga
