Reference no: EM13312927

The sun took 30 million years to evolve from a collapsing cloud core to a star, with 10 million of those years spent on it hayashi track. it will spend a total of 10 billion years on the main sequence. suppose we were to compress the suns main-sequence. suppose we were to compress main-sequence lifetime into just a single day. how long would the total collapse phase last? b.how long would the sun spend on its hayashi track?
