Surviving a pulsar

I cannot find any survival guide for the event that a pulsar scorches earth's surface with enough force to burn people to ashes but letting tree seeds grow in the ashes. No breathable air due to fires. Partially blocked sunlight.

How does one select the right type of protection?

How much time might we have to take cover?

What might the indirect effects be and how would one prepare for them?

In your under ground shelter and for a good supply of "fresh air", you could always use the same principle of how Submarines get fresh oxygen for 24 hours to fill the whole Submarine from a gallon of water..

Using electrolysis, you separate the Hydrogen from the Oxygen, collecting the fresh Oxygen to breathe..
Below is a picture of an electrolysis machine for separating the H20 :cool:

Such a pulsar would completely remove the entire atmosphere of the Earth.
So now the question is, why would you WANT to "survive" such a thing, and what does it MEAN to "survive" one?

Maybe become Aquaman and build an underwater city. Then wait millions of years until primitive lifeforms on the south pole have generated a new sky.

But Hartey, it could have been a tiny piece of a rotating neutron star, emitting tiny EM pulses around 175 Mhz, which is a frequency ive been told about...One of my transceivers covers the amateur radio frequencies from 144 Mhz continuously through to 440 Mhz...With a suitable RF kilowatt amplifier i could "dampen" those pesky radio pulses on 175 Mhz or any other frequency upto 440 Mhz :eek: :D
 
And would pass harmless, at least to your body.

The OP's pulsar is strong enough to burn people to ashes. That kind would strip the atmosphere right off the planet.

If that were to happen, would the oceans instantly 100% boil away? Even in the deepest underwater regions?

The ocean is 1-4 km deep, so there is a lot of mass per surface that must reach 100°C to boil off. This would need the equivalent energy of heating a body (1 dm) to 40 million °C.

Nope! No atmosphere reduces the boiling point to ambient temperature. Anything above freezing would immediately turn to gas until sufficient air pressure exists to increase the boiling point. We know this because we use this procedure called freeze drying to dehydrate food for packaging.

This assumes that water is not deep enough to hold its own pressure like a heavy atmosphere. Around 40 meter of water should be one atmospheric pressure.
