DOI: 10.1002/asna.201913620
Abstract: X-ray observations of Young Stellar Objects (YSOs) have shown several complex phenomena at work.In recent years a few X-ray programs based on long, continuous and, sporadically, simultaneous coordinated multi-wavelengths observations have paved the way to… read more here.

DOI: 10.1007/s11214-020-00664-z
Abstract: Recent observations have suggested that circumstellar disks may commonly form around young stellar objects. Although the formation of circumstellar disks can be a natural result of the conservation of angular momentum in the parent cloud,… read more here.

DOI: 10.1103/physrevd.102.124045
Abstract: Using a simple model of low-mass stellar objects we have shown modified gravity impact on their early evolution, such as Hayashi tracks, radiative core development, effective temperature, masses, and luminosities. We have also suggested that… read more here.
