SUMMARY

This discussion centers on the habitability of planets orbiting flare red dwarf stars and the potential survival of humanoid life forms in such environments. It concludes that while short-term exposure to red dwarf flares is survivable due to atmospheric protection, long-term effects such as atmospheric erosion pose significant risks. The Teegarten system is highlighted as a notable example where potentially habitable planets may lose their atmospheres over less than a billion years due to repeated flares. The conversation emphasizes the need for intelligent life forms to adapt to these conditions, potentially developing protective measures against solar flares.

PREREQUISITES
  • Understanding of red dwarf stars and their flare characteristics
  • Knowledge of atmospheric science and erosion processes
  • Familiarity with the Teegarten system and its planetary characteristics
  • Basic concepts of astrobiology and life adaptation to extreme environments
NEXT STEPS
  • Research the effects of solar flares on planetary atmospheres
  • Study the habitability of exoplanets in red dwarf systems
  • Explore astrobiological adaptations of life forms in extreme environments
  • Investigate experimental methods for testing life potential on moons like Europa
USEFUL FOR

Astronomers, astrobiologists, and science fiction writers interested in the implications of life existing around red dwarf stars and the challenges posed by stellar flares.

I was reading about how red dwarf stars are typically flare stars. So if there were humanoids that were like us on an Earth-like planet in a such red dwarf system - i.e., and were accustomed to the temperature of Earth, etc. - would the flare heat up the planet to be too hot for life? Alternatively, this question could be stated "if the Earth were somehow hyperspaced into an orbit around such a red dwarf system such that it had the same temperature as Earth has around Sol, would the flares cause the temperature to spike enough to kill us".

Basically, red dwarf flares are survivable in short term. X-ray flare fluxes are deadly outside of atmosphere, but are effectively blocked before reaching surface.
The habitability concerns are are mostly about long-term effect - i.e. atmosphere erosion. Planets orbiting flare stars (most notably potentially habitable planets in Teegarten system) may lose even dense atmospheres on the timescales of less than billion years, because of impulse heating of upper layers by repeating flares.
 
We can discuss the effect on humans, which are real, but not on "humanoids" which are fictional,

Well, by "humanoid" I meant some creature that is accustomed to conditions on Earth, had the sam elevel of corporeal robustness, and that had the intelligence to do things to mitigate the situation. For all intents & purposes, these humanoids could be considered humans.
 
I should say that I believe that "we are not alone".

This implies that life evolved on this hypothetical system including:

If intelligent life evolved and thrived under a variable star; such organisms, ipso facto, would be adapted to local conditions with appropriate protections from solar flares such as developing under atmosphere, underground, underwater, etc.

While this thread of reasoning approaches speculation, we humans should be able to test an analogue system in a reasonable length of time by conducting experiments substituting Jupiter for the red dwarf star and sampling plumes from Europa and similar satellites to detect life.
