Using rotation rates to map recent star birth

2

The rotation rate of stars can inform models of stellar age and identify young stars that have recently formed. Using rotation periods of the 16,000 stars in the Cygnus field...

Performing asteroseismology in the time domain

3

Asteroseismology can unlock stellar properties such as mass and radius independently from other methods. Until recently, asteroseismic analyses were only carried out in the frequency domain, by using Fourier Transforms...

Building a homogeneous catalog of K2 planets

2

Homogeneous planet catalogs enable the accurate study of the occurrence rates of planets. Although the first four years of Kepler data have been searched thoroughly by the official Kepler pipeline...

Many of the pixel masks observed by Kepler contain more than one star. These overlooked background stars potentially present opportunities to find new exoplanet candidates. Most planet search pipelines focus...

Accurately measuring occurrence rates of exoplanets not only provides insight into the prevalence of Earth-like planets in the universe, but also allows us to better design future missions for planet...

Constraining key properties of asteroids, such as rotation rate and shape, can further our understanding of the history of our own solar system. The K2 mission targeted 366 small Solar...

Measuring the mass of black holes in active galactic nuclei (AGN) can prove challenging. Understanding the mass of black holes in other galaxies informs our models of galaxy formation in...

Amongst many science opportunities, supernovae offer the opportunity to investigate stellar composition and understand mechanisms that drive the evolution of the galaxy. However, supernovae are best understood by observing and...

Statistical samples of stellar ages and compositions of red giants offer the opportunity to study the structure and evolution of the Galaxy, i.e. they enable Galactic Archaeology (Miglio et al....

Contemporaneous color photometry can unlock the potential of studies of stellar variability and dusty disks, as well as enabling the identification of exoplanet false positives. During K2 Campaigns 16 and...
