Freeze-out Effects in Hydrogen and Helium Lines of SN 1987A at the Early Photospheric Epoch
V. P. Utrobin, N. N. Chugai
We have developed a time-dependent model of ionization, excitation and energy balance of SN 1987A atmosphere at the photospheric epoch to study early behavior of hydrogen and heliu…

Ionization freeze-out and barium problem in supernova 1987A
V. P. Utrobin, N. N. Chugai
We have shown that in the atmosphere of SN 1987A level populations of hydrogen are mostly controlled by an ionization freeze-out and ion-molecular processes up to 40 days. The ioni…
