چکیده
We investigate the effect of population III (Pop III) stars supernova explosion (SN) on high redshifts reionization history using latest Planck data. It is predicted that massive Pop $(130\text{ }\text{ }{M}_{\ensuremath{\bigodot}}\ensuremath{\le}M\ensuremath{\le}270\text{ }{M}_{\ensuremath{\bigodot}})$ explode energetically at end their stellar life as pair-instability supernovae (PISNe). In explosion, remnants grow hot ionized bubbles and enhance ionization fraction in early stage history. This enhancement affects optical depth cosmic microwave background (CMB) generates additional anisotropy CMB polarization large scales. Therefore, analyzing data allows us to examine star SNe abundance progenitors, stars. order model supernova(SN) contribution reionization, we introduce a new parameter $\ensuremath{\zeta}$, which relates collapse Universe. Using Markov chain Monte Carlo method with data, obtain constraint our parameter, $\ensuremath{\zeta}$. Our tells observed consistent PISNe from formation rate initial mass function recent cosmological simulations. also suggest combining further observations late history, such redshift quasi-stellar object (QSO) observations, can provide tighter constraints important information nature

Population III Star Formation and IMF
We review recent 3D cosmological hydrodynamic simulations of primordial star formation from cosmological initial conditions (Pop III.1) and from initial conditions that have been altered by radiative feedback from stellar sources (Pop III.2). We concentrate on simulations that resolve the formation of the gravitationally unstable cloud cores in mini-halos over the mass range 105 < M/M⊙ < 107 an...
متن کاملSupernova Explosions and Neutron Star Formation
The current picture of the collapse and explosion of massive stars and the formation of neutron stars is reviewed. According to the favored scenario, however by no means proven and undisputed, neutrinos deposit the energy of the explosion in the stellar medium which surrounds the nascent neutron star. Observations, in particular of Supernova 1987A, suggest that mixing processes play an importan...
متن کاملMagneto-Hydrodynamics of Population III Star Formation
Jet driving and fragmentation process in collapsing primordial cloud are studied using three-dimensional MHD nested grid simulations. Starting from a rotating magnetized spherical cloud with the number density of nc ≃ 10 cm, we follow the evolution of the cloud up to the stellar density nc ≃ 10 cm. We calculate 36 models parameterizing the initial magnetic and rotational energies (γ0, β0). In t...
متن کاملRadiative Regulation of Population III Star Formation
We explore the impact of ultraviolet (UV) radiation from massive Population III (Pop III) stars of 25, 40, 80, and 120 M⊙ on the subsequent Pop III star formation. In this paper, particular attention is paid to the dependence of radiative feedback on the mass of source Pop III star. UV radiation from the source star can work to impede the secondary star formation through the photoheating and ph...
متن کاملSingle and binary evolution of Population III stars and their supernova explosions
We present stellar evolution calculations for Population III stars for both singleand binarystar evolutions. Our models include 10and 16.5-M single stars and a 10-M model star that undergoes an episode of accretion resulting in a final mass of 16.1 M . For comparison, we present the evolution of a solar heavy element abundance model. We use the structure from late-stage evolution models to calc...
