On using photometric data from Kepler to study starspots, and to measure differential rotation rates.
Do you own a digital single-lens reflex (DSLR) camera? The authors of today’s paper do. They used it for astronomy. They used it for science.
Our current best radial velocities are precise to about 1m/s. How do we make the step towards achieving 10cm/s precision?
Advanced observational tools such as ALMA allow the detection of complex organic molecules – the building blocks of life. However, how and where they are formed is still unknown.
Heavy stars live like rock stars: they live fast, become big, and die young. Low mass stars, on the other hand, are more persistent, and live longer. Fusing hydrogen slow and steady wins the stellar age-race.
Cepheids are bright enough that we can use them to measure distances to other galaxies, but their luminosities also makes detecting their companions particularly difficult. So how do astronomers find their uncover their secret partners? Today’s paper takes a look…
