Pulsar is also called as<u> neutron stars or white dwarfs.</u> These are formed after the supernova explosion. Their mass is higher than a normal star. And the most different thing we find in pulsar is that, in a pulsar the proton and electrons combine themselves to form a neutron. That's why this is also called as neutron star. After neutron or white dwarf the star goes to the black dwarf stage.
Remember when the core of the iron becomes iron rich that time it cannot sustain further nucleo synthesis process, that's why it goes for a supernova explosion. Which results the formation of neutron star or white dwarf, followed by black dwarf or black hole.
Answer: Is prone to desertification or drought.
Explanation: The Sahel region is located in Africa between the Sahara to the north and the Sudanian Savanna to the south.
The Sahel has a semi arid climate which is characterized by precipitation below potential evapotranspiration.
What this means is that the amount of water that would be evaporated and transpired by a specific crop or ecosystem is low. This region is prone to desertification or drought because of the low amount of water evaporated and transpirated in the region.
