  1. 1. Photometry of carbon star wind-modelsat solar & sub-solar metallicities

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Vlad Rastau; [2020]
    Keywords : C-type AGB; photometry; mass-loss;

    Abstract : Asymptotic giant branch stars (AGB) are cool, luminous stars withan initial mass of approximately 0.8 to 8 solar masses. Towards theend of their lives they undergo heavy mass loss, a process thoughtto be caused by dust-driven winds. When it comes to carbon-richAGB stars, i. READ MORE

  3. 2. Pulsation Properties in Asymptotic Giant Branch Stars

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Ofelia Norgren; [2019]
    Keywords : Astronomy; Asymptotic Giant Branch stars; Stellar Evolution; Variable Stars; Power Spectrum;

    Abstract : Asymptotic Giant Branch (AGB) stars are stars with low- to intermediate mass in a late stage in their stellar evolution. An important feature of stellar evolution is the ongoing nucleosynthesis, the creation of heavier elements. READ MORE

  4. 3. Dust driven winds of cool giant stars : dependency on grain size

    University essay from Teoretisk astrofysik

    Author : Filip Jennerholm Hammar; [2011]
    Keywords : stars: AGB; stars: atmospheres; stars: carbon; stars: mass loss; stars: grain size; asymptotiska jättegrenen; kolstjärnor; stjärnor: massförlust;

    Abstract : Aim. In this project, theoretical models of dust driven winds of asymptotic giant branch (AGB) stars with effective temperatures within a range of 2400 − 3200 [K] and relative carbon-to-oxygen abundance C/O > 1 are studied. READ MORE
