Astronomer CEO Andy Byron resigned after being caught on Kiss Cam with HR head at Coldplay concert, but legal experts say any potential lawsuit against Chris Martin would fail.

A second executive has resigned from tech company Astronomer following a Coldplay concert video that went viral and sparked online speculation and scrutiny. The company confirmed Thursday that Kristin Cabot, Astronomer's chief people officer, had submitted her resignation.
