Jeans escape describes atmospheric loss when molecular thermal velocity exceeds planet escape velocity, particularly important for light elements.

चरण-दर-चरण मार्गदर्शिका

  1. 1Input planet mass/radius, atmospheric temperature and composition
  2. 2Calculate escape velocity and thermal velocity
  3. 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.
