Internal rotation of red giants by asteroseismology

M. P. Di Mauro, D. Cardini, R. Ventura +12

We present an asteroseismic approach to study the dynamics of the stellar interior in red-giant stars by asteroseismic inversion of the splittings induced by the stellar rotation o…

Impulsive Laser Induced Alignment of Molecules Dissolved in Helium Nanodroplets

Dominik Pentlehner, Jens H. Nielsen, Alkwin Slenczka +2

We show that a 450 fs nonresonant, moderately intense, linearly polarized laser pulse can induce field-free molecular axis alignment of methyliodide molecules dissolved in a helium…
