We present a detailed analysis of the asteroseismic main-sequence benchmark star Dra A in the TESS northern CVZ. We aim to derive stellar mass and radius from asteroseismic mod…
Detecting Solar-Like Oscillations in the Highest Mass TESS Giants
Noah J. Downing, Madeline Howell, Marc H. Pinsonneault +4
Red-giant asteroseismology yields precise stellar parameters, making it a powerful tool for studying stellar structure and evolution, as demonstrated by the Kepler mission. However…
K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system
Jaroslav Merc, David Jones, Ana Escorza +22
K 1-6 has long been classified as a planetary nebula (PN) hosting a binary central star, yet it has remained poorly studied due to its faintness. The central star exhibits pronounc…
Hierarchically modelling Kepler dwarfs and subgiants to improve inference of stellar properties with asteroseismology
Alexander J. Lyttle, Guy R. Davies, Tanda Li +9
With recent advances in modelling stars using high-precision asteroseismology, the systematic effects associated with our assumptions of stellar helium abundance () and the mixi…
Weakened magnetic braking supported by asteroseismic rotation rates of Kepler dwarfs
Oliver J. Hall, Guy R. Davies, Jennifer van Saders +9
Studies using asteroseismic ages and rotation rates from star-spot rotation have indicated that standard age-rotation relations may break down roughly half-way through the main seq…
ROOSTER: a machine-learning analysis tool for Kepler stellar rotation periods
Sylvain N. Breton, Angela R. G. Santos, Lisa Bugnet +3
In order to understand stellar evolution, it is crucial to efficiently determine stellar surface rotation periods. An efficient tool to automatically determine reliable rotation pe…
The K2 Galactic Archaeology Program Data Release 2: Asteroseismic results from campaigns 4, 6, & 7
Joel C. Zinn, Dennis Stello, Yvonne Elsworth +18
Studies of Galactic structure and evolution have benefitted enormously from Gaia kinematic information, though additional, intrinsic stellar parameters like age are required to bes…
TESS Asteroseismology of Mensae: Benchmark Ages for a G7 Dwarf and its M-dwarf Companion
Ashley Chontos, Daniel Huber, Travis A. Berger +27
Asteroseismology of bright stars has become increasingly important as a method to determine fundamental properties (in particular ages) of stars. The Kepler Space Telescope initiat…
Robust asteroseismic properties of the bright planet host HD 38529
Warrick H. Ball, William J. Chaplin, Martin B. Nielsen +21
The Transiting Exoplanet Survey Satellite (TESS) is recording short-cadence, high duty-cycle timeseries across most of the sky, which presents the opportunity to detect and study o…
Investigating surface correction relations for RGB stars
Andreas Christ Sølvsten Jørgensen, Josefina Montalbán, Andrea Miglio +7
State-of-the-art stellar structure and evolution codes fail to adequately describe turbulent convection. For stars with convective envelopes, such as red giants, this leads to an i…
Optical and nanostructural insights of oblique angle deposited layers applied for photononic coatings
Florian Maudet, Bertrand Lacroix, Antonio J. Santos +10
Oblique angle deposition (OAD) is a nanostructuration method widely used to tune the optical properties of thin films. The introduction of porosity controlled by the deposition ang…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
Core-Envelope Coupling in Intermediate-Mass Core-Helium Burning Stars
Jamie Tayar, Paul G. Beck, Marc H. Pinsonneault +2
Stars between two and three solar masses rotate rapidly on the main sequence, and the detection of slow core and surface rotation in the core-helium burning phase for these stars p…
TESS Asteroseismology of the known red-giant host stars HD 212771 and HD 203949
Tiago L. Campante, Enrico Corsaro, Mikkel N. Lund +45
The Transiting Exoplanet Survey Satellite (TESS) is performing a near all-sky survey for planets that transit bright stars. In addition, its excellent photometric precision enables…
TOI-503: The first known brown dwarf-Am star binary from the TESS mission
Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76
We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…

Eric Michel, Kévin Belkacem, Benoît Mosser +13
The period 2035-50 considered in the ESA Voyage long-term plan will coincide with a series of foreseeable advances in the characterization of the stellar content of the Milky Way.…
On the importance of light scattering for high performances nanostructured antireflective surfaces
Florian Maudet, Bertrand Lacroix, Antonio J. Santos +8
An antireflective coating presenting a continuous refractive index gradient is theoretically better than its discrete counterpart because it can give rise to a perfect broadband tr…
