Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes
M. Wicker, Ł. Wyrzykowski, M. Hundertmark +49
The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…
Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey. IV. Lens Mass and Distance Measurements
Sean K. Terry, Etienne Bachelet, Farzaneh Zohrabi +54
As part of the Galactic Bulge Time Domain Survey (GBTDS), the Nancy Grace Roman Galactic Exoplanet Survey (RGES) will use microlensing to discover cold outer planets and free-float…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Ł. Wyrzykowski, P. J. Mikołajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
A close binary lens revealed by the microlensing event Gaia20bof
E. Bachelet, P. Rota, V. Bozza +24
During the last 25 years, hundreds of binary stars and planets have been discovered towards the Galactic Bulge by microlensing surveys. Thanks to a new generation of large-sky surv…
Gaia22dkvLb: A Microlensing Planet Potentially Accessible to Radial-Velocity Characterization
Zexuan Wu, Subo Dong, Tuan Yi +50
We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensin…
MOA-2020-BLG-208Lb: Cool Sub-Saturn Planet Within Predicted Desert
Greg Olmschenk, David P. Bennett, Ian A. Bond +74
We analyze the MOA-2020-BLG-208 gravitational microlensing event and present the discovery and characterization of a new planet, MOA-2020-BLG-208Lb, with an estimated sub-Saturn ma…
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…
A spectroscopic follow-up for Gaia19bld
E. Bachelet, P. Zielinski, M. Gromadzki +11
Due to their scarcity, microlensing events in the Galactic disk are of great interest and high-cadence photometric observations, supplemented by spectroscopic follow-up, are necess…
Gaia Early Data Release 3: The Galactic anticentre
Gaia Collaboration, T. Antoja, P. McMillan +417
We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of the Milky Way structure and evolution. We used astrometric positions, proper…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
Gaia18aen: First symbiotic star discovered by Gaia
J. Merc, J. Mikołajewska, M. Gromadzki +20
Besides the astrometric mission of the Gaia satellite, its repeated and high-precision measurements serve also as an all-sky photometric transient survey. The sudden brightenings o…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
OGLE-ing the Magellanic System: Cepheids in the Bridge
Anna M. Jacyszyn-Dobrzeniecka, I. Soszyński, A. Udalski +12
We present a detailed analysis of Magellanic Bridge Cepheid sample constructed using the OGLE Collection of Variable Stars. Our updated Bridge sample contains 10 classical and 13 a…
OGLE-ing the Magellanic System: RR Lyrae Stars in the Bridge
Anna M. Jacyszyn-Dobrzeniecka, P. Mróz, K. Kruszyńska +12
We use the extended and updated OGLE Collection of Variable Stars to thoroughly analyze distribution of RR Lyrae stars in the Magellanic Bridge. We use photometric metallicities to…
