Space telescopes

…for laser metrology in future large space telescopes, high-speed and secure space communications, sensing and power transfer. Research areas are chip-scale stable laser systems built with MEMS and nanophotonic technologies, such as silicon nitride on-chip etalons and waveguides, lithium niobate modulators, heterogeneous integration and packaging of photonic microdevices, on-chip atomic and molecular spectroscopy and vapour cells, and the supporting DC, RF and microwave electro

Conny Aerts explains how stellar oscillations measured by space telescopes reveal otherwise inaccessible interiors. Asteroseismology probes physical conditions and chemical composition, allowing more precise estimates of stellar sizes, masses and ages. The lecture connects these measurements to rapidly rotating stars that may end in supernovae and produce gravitational waves. It also examines how stellar seismology supports reconstruction of the Milky Way’s history and the characterisation of exoplanets.
