Other Solar Systems Around Other Stars

Other Solar Systems Around Other Stars. Stars form around other stars, in Open Star Clusters generally Exoplanets = planets around other stars How do we discover them? How do selection effects bias our results? What are these exoplanets like? Can we detect their atmospheres, climate?.

Doppler shifts (  v n ) can’t distinguish between flows paral-lel to B , perpendicular to B , or in an intermediate direction. Since  B n /  t =  x ( v x B ), flows v || along B do not affect  B n /  t, so “inductive flow” methods only determine v  .
