Debris disks: structure, composition, and variability

AM Hughes, G Duchêne… - Annual Review of …, 2018 - annualreviews.org
Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

Exozodiacal clouds: hot and warm dust around main sequence stars

Q Kral, AV Krivov, D Defrère, R van Lieshout… - Astronomical …, 2017 - Taylor & Francis
A warm/hot dust component (at temperature 300 K) has been detected around 20% of A, F,
G, K stars. This component is called 'exozodiacal dust'as it presents similarities with the …

The dust grain size–stellar luminosity trend in debris discs

N Pawellek, AV Krivov - Monthly Notices of the Royal …, 2015 - academic.oup.com
The cross-section of material in debris discs is thought to be dominated by the smallest
grains that can still stay in bound orbits despite the repelling action of stellar radiation …

Rotation of Low-mass Stars in Upper Centaurus–Lupus and Lower Centaurus–Crux with TESS

LM Rebull, JR Stauffer, LA Hillenbrand… - The Astronomical …, 2022 - iopscience.iop.org
We present stellar rotation rates derived from Transiting Exoplanet Survey Satellite (TESS)
light curves for stars in Upper Centaurus–Lupus (UCL;∼ 136 pc,∼ 16 Myr) and Lower …

The high-albedo, low polarization disk around HD 114082 that harbors a Jupiter-sized transiting planet-Constraints from VLT/SPHERE completed with TESS, Gaia …

N Engler, J Milli, R Gratton, S Ulmer-Moll… - Astronomy & …, 2023 - aanda.org
Aims. We present new optical and near-infrared images of the debris disk around the F-type
star HD 114082 in the Scorpius-Centaurus OB association. We obtained direct imaging …

A new sample of warm extreme Debris disks from the ALLWISE catalog

A Moór, P Ábrahám, G Szabó, K Vida… - The Astrophysical …, 2021 - iopscience.iop.org
Extreme debris disks (EDDs) are rare systems with peculiarly large amounts of warm dust
that may stem from recent giant impacts between planetary embryos during the final phases …

The HIP 79977 debris disk in polarized light

N Engler, HM Schmid, C Thalmann… - Astronomy & …, 2017 - aanda.org
Context. Debris disks are observed around 10 to 20% of FGK main-sequence stars as
infrared excess emission. They are important signposts for the presence of colliding …

Trends in Silicates in the β Pictoris Disk

CX Lu, CH Chen, BA Sargent, DM Watson… - The Astrophysical …, 2022 - iopscience.iop.org
While β Pic is known to host silicates in ring-like structures, whether the properties of these
silicate dust vary with stellocentric distance remains an open question. We re-analyze the β …

Revisiting the pulsational characteristics of the exoplanet host star β Pictoris

K Zwintz, DR Reese, C Neiner, A Pigulski… - Astronomy & …, 2019 - aanda.org
Context. Exoplanet properties crucially depend on the parameters of their host stars: more
accurate stellar parameters yield more accurate exoplanet characteristics. When the …

An Exo–Kuiper Belt with an Extended Halo around HD 191089 in Scattered Light
