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…

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…

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…

New Periodograms Separating Orbital Radial Velocities and Spectral Shape Variation

Avraham Binnenfeld, Sahar Shahaf, Richard I. Anderson +1

We present new periodograms that are effective in distinguishing Doppler shift from spectral shape variability in astronomical spectra. These periodograms, building upon the concep…

USuRPER: Unit-Sphere Representation PERiodogram for full spectra

Avraham Binnenfeld, Sahar Shahaf, Shay Zucker

We introduce an extension of the periodogram concept to time-resolved spectroscopy. USuRPER -- Unit Sphere Representation PERiodogram -- is a novel technique which opens new horizo…
