Constraining an exoplanets magnetic field using star-planet interactions
D. Revilla, P. J. Amado, R. Luque +17
Theory predicts that a planet with a sufficiently strong magnetic field orbiting close to its host star could induce star-planet magnetic interactions. This is potentially observab…
Spectroscopic Alerts for the Time-Domain Era
Alejandra Melo, Paula Sanchez-Saez, Valentin D. Ivanov +13
Time-domain astronomy is entering an era of unprecedented discovery driven by wide-field, high-cadence surveys such as LSST, Roman, Euclid, SKA, and PLATO. While some of these faci…
White Dwarf Binaries: Probes of Future Astrophysics
Anna F. Pala, Roberto Raddi, Alberto Rebassa-Mansergas +25
White dwarf binaries are fundamental astrophysical probes. They represent ideal laboratories to test the models of binary evolution, which also apply to the sources of gravitationa…
Transients as Determinants of Habitability
Fatemeh Zahra Majidi, Katia Biazzo, Maria Tsantaki +7
Stellar magnetic activity, manifested through spots (faculae and flares), fundamentally shapes the exoplanets' environments. For low-mass stars in particular, where most habitable-…
Toward the time-domain spectroscopic study of the dynamic life of stars: from accretion to magnetic activity
Fatemeh Zahra Majidi, Amelia Bayo, Marc Audard +11
Stars and planets can be seen as the second fundamental building blocks of baryons in the universe (only second to the dust and gas in molecular clouds). Their formation involves d…
The VELOCE modulation zoo III. Detecting additional pulsation modes in optical spectra of classical Cepheids using semi-partial distance correlation periodograms
Kent Barbey, Richard Irving Anderson, Giordano Viviani +5
Known for their large amplitude radial pulsations, classical Cepheids are critical standard candles in astrophysics. However, they also exhibit various pulsational irregularities a…
GJ 2126 b: A highly eccentric Jovian exoplanet
Arbel Schorr, Avraham Binnenfeld, Shay Zucker
We report the discovery of GJ 2126 b, a highly eccentric (e = 0.85) Jupiter-like planet orbiting its host star every 272.7 days. The planet was detected and characterized using 112…
Wide Binary Orbits are Preferentially Aligned with the Orbits of Small Planets, but Probably Not Hot Jupiters
Sam Christian, Andrew Vanderburg, Juliette Becker +28
Studying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 AU) can shed light on how planets form and evolv…
Adaptation of the Phase Distance Correlation Periodogram to Account for Measurement Uncertainties
Avraham Binnenfeld, Sahar Shahaf, Shay Zucker
We present an improvement of the phase distance correlation (PDC) periodogram to account for uncertainties in the time-series data. The PDC periodogram introduced in our previous p…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Asteroid orbital solution. Properties and assessment
Gaia Collaboration, P. David, F. Mignard +2
Context. We report the exploitation of a sample of epoch astrometry for 157 000 asteroids, the same object in the Gaia Data Release 3, extended over the time coverage planned for t…
Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
Gaia Collaboration, A. Krone-Martins, C. Ducourant +398
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
Identification of the Top TESS Objects of Interest for Atmospheric Characterization of Transiting Exoplanets with JWST
Benjamin J. Hord, Eliza M. -R. Kempton, Thomas Mikal-Evans +142
JWST has ushered in an era of unprecedented ability to characterize exoplanetary atmospheres. While there are over 5,000 confirmed planets, more than 4,000 TESS planet candidates a…
Model Independent Periodogram for Scanning Astrometry
Avraham Binnenfeld, Sahar Shahaf, Shay Zucker
We present a new periodogram for periodicity detection in one-dimensional time-series data from scanning astrometry space missions, like Hipparcos or Gaia. The periodogram is non-p…
Gaia Data Release 3. Summary of the variability processing and analysis
L. Eyer, M. Audard, B. Holl +55
Context. Gaia has been in operations since 2014. The third Gaia data release expands from the early data release (EDR3) in 2020 by providing 34 months of multi-epoch observations t…
The Detection of Transiting Exoplanets by Gaia
Aviad Panahi, Shay Zucker, Gisella Clementini +14
