Jeans escape describes atmospheric loss when molecular thermal velocity exceeds planet escape velocity, particularly important for light elements.
Guida passo passo
- 1Input planet mass/radius, atmospheric temperature and composition
- 2Calculate escape velocity and thermal velocity
- 3Estimate atmospheric escape timescale
Esempi risolti
Ingresso
Earth H/He at 6000K exosphere
Risultato
H escapes easily, He slowly, O/N retain
Why Earth lost primordial atmosphere
Errori comuni da evitare
- ✕Neglecting temperature gradient with altitude
- ✕Assuming steady escape rate
Domande frequenti
Does Mars still lose atmosphere?
Yes, slowly; weak gravity and solar wind accelerate loss.
