FBS 2213+421, an extremely red object with C-rich characteristics

It was confirmed spectroscopically that FBS 2213+421 belongs to the group of ECS. Adopting as a Long-Period Mira-type variable, the pulsation period and mass-loss rate are estimated using K - [12] color index. Luminosities are derived using a revised P - L relation obtained for Galactic carbon Mira-...

Zusammenfassung:It was confirmed spectroscopically that FBS 2213+421 belongs to the group of ECS. Adopting as a Long-Period Mira-type variable, the pulsation period and mass-loss rate are estimated using K - [12] color index. Luminosities are derived using a revised P - L relation obtained for Galactic carbon Mira-variables.
