1. Introduction

    1. Is there something wrong with the standard solar model?

    2. More precise statement of the problem

    3. Possible approaches to the problem

  2. Could solar metallicity problem reflect the presence of dark matter in solar core?

    1. Could "cold fusion" come in rescue?

    2. Evidence for the tunnelling of electrons in nanoscales

    3. Could Sun contain dark magnetic flux tubes carrying dark matter?

  3. Some anomalies of astrophysics from TGD point of view

    1. Youthful Oldies

    2. Helium problem and CNO problem: two anomalies explained by dark fusion

    3. Basic organic molecules emerge much earlier than they should

    4. Hyperon problem of neutron star physics

  4. Conclusions
