Asteroseismology and interferometry of the F7V spectroscopic binary Draconis A in the TESS CVZ

Jonatan Rudrasingam, Mikkel N. Lund, Frank Grundahl +26

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…

Not all nitrogen-rich field stars originate from globular clusters

Ellen I. Leitinger, Andrea Miglio, Josefina Montalbán +7

Globular clusters (GCs) are important tracers of the early Galactic assembly process, with part of their stars showing distinct chemical abundance patterns. When such stars are fou…

AGN in Gaia Alerts: from flares to Changing Look Quasars

M. Dennefeld, T. Pursimo, C. Carvalho +11

The Gaia Alerts system is providing alerts on a variety of objects displaying a significant photometric change detected by the Gaia satellite from one passage to the next one over…

Attempting an accurate age estimate of the open cluster NGC 6633 using CoRoT and Gaia

K. Brogaard, A. Miglio, T. Arentoft +5

Asteroseismology of solar-like oscillations in giant stars allow the derivation of their masses and radii. For members of open clusters, this provides an age of the cluster that sh…

DUETS: Setting expectations for asteroseismic binaries and binary products with synthetic populations

A. Mazzi, J. S. Thomsen, A. Miglio +5

Asteroseismology gives us the opportunity to better characterize binaries and their products, and shed light on their role in Galactic populations. We estimate occurrence rates, ma…

Advancing accuracy in age determinations of old-disk stars using an oscillating red giant in an eclipsing binary

J. S. Thomsen, A. Miglio, K. Brogaard +26

The study of resonant oscillation modes in low-mass red giant branch stars enables their ages to be inferred with exceptional (10%) precision, unlocking the possibility to re…

Connecting integrated RGB mass loss from asteroseismology and globular clusters

K. Brogaard, A. Miglio, W. E. van Rossem +2

Context. Asteroseismic investigations of solar-like oscillations in giant stars enable the derivation of their masses and radii. For mono-age mono-metallicity populations of stars…

K2 results for "young" -rich stars in the Galaxy

V. Grisoni, C. Chiappini, A. Miglio +11

The origin of apparently young -rich stars in the Galaxy is still a matter of debate in Galactic archaeology, whether they are genuinely young or might be products of binary evo…

An asteroseismic age estimate of the open cluster NGC 6866 using Kepler and Gaia

K. Brogaard, T. Arentoft, A. Miglio +10

Asteroseismology of solar-like oscillations in giant stars allow the derivation of their masses and radii. For members of open clusters this allows an age estimate of the cluster w…

Spectral Type and Geometric Albedo of (98943) 2001 CC21, the Hayabusa2# Mission Target

Jooyeon Geem, Masateru Ishiguro, Mikael Granvik +18

We conducted optical polarimetry and near-infrared spectroscopy of JAXA's Hayabusa2# mission target, (98943) 2001 CC21, in early 2023. Our new observations indicated that this aste…

Establishing the accuracy of asteroseismic mass and radius estimates of giant stars. II. Revised stellar masses and radii for KIC 8430105

Jeppe Sinkbæk Thomsen, Karsten Brogaard, Torben Arentoft +6

Asteroseismic scaling relations can provide high-precision measurements of mass and radius for red giant (RG) stars displaying solar-like oscillations. Their accuracy can be valida…
