Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
S. Sulis, M. Lendl, H. Cegla +83
Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and evolutionary state. In this study, we…
Missing Metals in DQ Stars; a Compelling Clue to their Origin
J. Farihi, P. Dufour, T. G. Wilson
White dwarf stars frequently experience external pollution by heavy elements, and yet the intrinsically carbon-enriched DQ spectral class members fail to exhibit this phenomenon, r…
The EBLM project -- VIII. First results for M-dwarf mass, radius and effective temperature measurements using CHEOPS light curves
M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +93
The accuracy of theoretical mass, radius and effective temperature values for M-dwarf stars is an active topic of debate. Differences between observed and theoretical values have r…
Carbon-enhanced stars with short orbital and spin periods
L. J. Whitehouse, J. Farihi, I. D. Howarth +5
Many characteristics of dwarf carbon stars are broadly consistent with a binary origin, including mass transfer from an evolved companion. While the population overall appears to h…
Three Years of HARPS-N High-Resolution Spectroscopy and Precise Radial Velocity Data for the Sun
X. Dumusque, M. Cretignier, D. Sosnowska +35
The solar telescope connected to HARPS-N has been observing the Sun since the summer of 2015. Such high-cadence, long-baseline data set is crucial for understanding spurious radial…
The dust never settles: collisional production of gas and dust in evolved planetary systems
Andrew Swan, Jay Farihi, Thomas G. Wilson +1
Multi-epoch infrared photometry from Spitzer is used to monitor circumstellar discs at white dwarfs, which are consistent with disrupted minor planets whose debris is accreted and…
Most white dwarfs with detectable dust discs show infrared variability
Andrew Swan, Jay Farihi, Thomas G. Wilson
Archival data from the WISE satellite reveals infrared flux variations of tens of per cent around numerous dusty white dwarfs. Data spanning more than seven years reveal more than…
Dwarf carbon stars are likely metal-poor binaries and unlikely hosts to carbon planets
Lewis J. Whitehouse, J. Farihi, P. J. Green +2
Dwarf carbon stars make up the largest fraction of carbon stars in the Galaxy with around 1200 candidates known to date primarily from the Sloan Digital Sky Survey. They either pos…
