The Enigma of Gaia18cjb: a Rare Hybrid of FUor and EXor?
Eleonora Fiorellino, Peter Abraham, Agnes Kospal +28
Context. Gaia18cjb is one of the Gaia-alerted eruptive young star candidates which has been experiencing a slow and strong brightening during the last 13 years, similar to some FU…
Photometric and spectroscopic study of the burst-like brightening of two Gaia-alerted young stellar objects
Zsófia Nagy, Péter Ábrahám, Ágnes Kóspál +18
Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia Science Alerts system…
Recurrent strong outbursts of an EXor-like young eruptive star Gaia20eae
Fernando Cruz-Sáenz de Miera, Ágnes Kóspál, Péter Ábrahám +21
We present follow-up photometric and spectroscopic observations, and subsequent analysis of Gaia20eae. This source triggered photometric alerts during 2020 after showing a 3…
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…
Rotational modulation and single g-mode pulsation in the B9pSi star HD174356?
Z. Mikulasek, E. Paunzen, S. Huemmerich +19
Chemically peculiar (CP) stars of the upper main sequence are characterised by specific anomalies in the photospheric abundances of some chemical elements. The group of CP2 stars,…
Observing the PTPS Sample of Evolved Exoplanet Host Candidates Using the NPOI
Ellyn K. Baines, J. Thomas Armstrong, Henrique R. Schmitt +6
We plan to measure the angular diameters of a sample of Penn State-Torun Planet Search (PTPS) giant exoplanet host star candidates using the Navy Precision Optical Interferometer.…
