This study examines the possibility of starting the process of collapsing and forming stars from a fractional molecular cloud. Although the Verlinde's approach is employed to derive the corresponding gravitational potential, the results are easily generalizable to other gravitational potential proposals for fractional systems. It is due to the fact that the different methods, despite the difference in the details of results, all obtain power forms for the potential in terms of radius. An essential result of this analysis is the derivation of the corresponding Jeans mass limit, which is a crucial parameter in understanding the formation of stars. The study shows that the Jeans mass of a cloud in fractional gravity is much smaller than the traditional value. In addition, the study also determines the burning temperature of the resulting star using the Gamow theory. This calculation provides insight into the complex processes that govern the evolution of these celestial bodies. Finally, the study briefly discusses the investigation of hydrostatic equilibrium, a crucial condition that ensures the stability of these fractional stars. It also addresses the corresponding Lane--Emden equation, which is pivotal in understanding this equilibrium.

  1. Fractional entropy of the Brown-Kucha\v{r} dust in fractional anti-de Sitter quantum gravity

    gr-qc 2025-01 conditional novelty 5.0 of 10

    In flat AdS quantum cosmology with Brown-Kuchar dust, the fractional Wheeler-DeWitt equation yields mass and entropy spectra scaling as (n+1/2)^(alpha/2), with a fractal mass dimension D = 3 alpha / 2.

  2. Fractional Schwarzschild-Tangherlini black hole with a fractal event horizon

    gr-qc 2025-06 reject novelty 4.0 of 10

    A fractional Wheeler-DeWitt equation yields D-dimensional Schwarzschild-Tangherlini black holes, with the horizon called fractal and the temperature set by an arbitrary parameter alpha.

  3. Generalized Brans-Dicke theory from Verlinde's entropic gravity

    gr-qc 2025-06 reject novelty 3.0 of 10

    Combining q-deformed statistics with Verlinde entropic gravity yields Brans-Dicke equations with a constant rescaling of G and omega, so no new gravitational dynamics appear.
