Jeans escape describes atmospheric loss when molecular thermal velocity exceeds planet escape velocity, particularly important for light elements.
चरण-दर-चरण मार्गदर्शिका
- 1Input planet mass/radius, atmospheric temperature and composition
- 2Calculate escape velocity and thermal velocity
- 3Estimate atmospheric escape timescale
हल किए गए उदाहरण
इनपुट
Earth H/He at 6000K exosphere
परिणाम
H escapes easily, He slowly, O/N retain
Why Earth lost primordial atmosphere
सामान्य गलतियां जिनसे बचना है
- ✕Neglecting temperature gradient with altitude
- ✕Assuming steady escape rate
अक्सर पूछे जाने वाले प्रश्न
Does Mars still lose atmosphere?
Yes, slowly; weak gravity and solar wind accelerate loss.
