A radio transmitter on a space probe can do more than just communicate and send data home. With the right expertise, it also provides radio astronomers with an excellent opportunity to carry out original scientific measurements.
ESA's Gaia mission released a goldmine of knowledge about our galaxy and beyond. Four hundred scientists worked on the mission’s latest ‘focused product release’ (FPR), with the active involvement of eight researchers from the Observatory.
Measuring the masses of stars is not always easy, and for the RR Lyrae-type variable stars, in particular, there has been no good way to do this. Our researchers are the first to determine the masses of such stars using seismic models.
