Only Gill, my 75-year-old friend, could get away with saying that. Tears quickly turned to roaring laughter as we toasted to moving on — and to not needing a man to acquire farm animals.
Using this technique, ages for the Pleiades of between 75 and 150 million years have been estimated. The wide spread in estimated ages is a result of uncertainties in stellar evolution models, which include factors such as convective overshoot , in which a convective zone within a star penetrates an otherwise non-convective zone, resulting in ...
