The occurrence and architecture of exoplanetary systems

JN Winn, DC Fabrycky - Annual Review of Astronomy and …, 2015 - annualreviews.org
The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

Post-main-sequence planetary system evolution

D Veras - Royal Society Open Science, 2016 - royalsocietypublishing.org

represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main …

A giant planet candidate transiting a white dwarf

A Vanderburg, SA Rappaport, S Xu, IJM Crossfield… - Nature, 2020 - nature.com
Astronomers have discovered thousands of planets outside the Solar System, most of which
orbit stars that will eventually evolve into red giants and then into white dwarfs. During the …

Hot subluminous stars

U Heber - Publications of the Astronomical Society of the Pacific, 2016 - iopscience.iop.org
Hot subluminous stars of spectral type B and O are core helium-burning stars at the blue end
of the horizontal branch or have evolved even beyond that stage. Most hot subdwarf stars …

The frequency of planetary debris around young white dwarfs

D Koester, BT Gänsicke, J Farihi - Astronomy & Astrophysics, 2014 - aanda.org
Context. Heavy metals in the atmospheres of white dwarfs are thought in many cases to be
accreted from a circumstellar debris disk, which was formed by the tidal disruption of a rocky …

Protoplanetary disk lifetimes vs. stellar mass and possible implications for giant planet populations

Á Ribas, H Bouy, B Merín - Astronomy & Astrophysics, 2015 - aanda.org
Aims. We study the dependence of protoplanetary disk evolution on stellar mass using a
large sample of young stellar objects in nearby young star-forming regions. Methods. We …

Dawes review 6: the impact of companions on stellar evolution

O De Marco, RG Izzard - Publications of the Astronomical Society of …, 2017 - cambridge.org

stellar evolution. New discoveries have underlined the role of binary star interactions in a …

Precise radial velocities of giant stars-VII. Occurrence rate of giant extrasolar planets as a function of mass and metallicity

S Reffert, C Bergmann, A Quirrenbach… - Astronomy & …, 2015 - aanda.org
Context. We have obtained precise radial velocities for a sample of 373 G and K type giants
at Lick Observatory regularly over more than 12 years. Planets have been identified around …

The chemical diversity of exo-terrestrial planetary debris around white dwarfs

BT Gänsicke, D Koester, J Farihi… - Monthly Notices of …, 2012 - academic.oup.com
Abstract We present Hubble Space Telescope (HST) ultraviolet spectroscopy of the white
dwarfs PG 0843+ 516, PG 1015+ 161, SDSS 1228+ 1040, and GALEX 1931+ 0117, which …

The Apparently Decaying Orbit of WASP-12

KC Patra, JN Winn, MJ Holman, L Yu… - arXiv preprint arXiv …, 2017 - arxiv.org
We present new transit and occultation times for the hot Jupiter WASP-12b. The data are
compatible with a constant period derivative: $\dot {P}=-29\pm 3$ ms yr $^{-1} $ and $ P/\dot …
