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…
Uncovering astrometric black hole binaries with massive main-sequence companions with Gaia
S. Janssens, T. Shenar, H. Sana +6
The hunt for compact objects is on. Rarely seen massive binaries with a compact object are a crucial phase in the evolution towards compact object mergers. In Gaia data release 3 (…
Systematic search for long-term transit duration changes in Kepler transiting planets
Sahar Shahaf, Tsevi Mazeh, Shay Zucker +1
Holczer, Mazeh, and collaborators (HM+16) used the Kepler four-year observations to derive a transit-timing catalog, identifying 260 Kepler objects of interest (KOI) with significa…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
