Precise physical parameters of three late-type eclipsing binary giant stars in the Large Magellanic Cloud

Autor: García, G. Rojas, Graczyk, D., Pietrzyński, G., Gałan, C., Gieren, W., Thompson, I., Suchomska, K., Kałuszyński, M., Soszyński, I., Udalski, A., Karczmarek, P., Narloch, W., Górski, M., Wielgórski, P., Zgirski, B., Miller, N., Hajdu, G., Pilecki, B., Taormina, M., Lewis, M.

Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical parameters in a near-model-independent way for a number of systems consisting

CHEOPS is a space telescope specifically designed to monitor transiting exoplanets orbiting bright stars. In September 2023, CHEOPS completed its nominal mission and remains in excellent operational conditions. The mission has been extended until the

Multi-wavelength detection of an ongoing FUOr-type outburst on a low-mass YSO

Autor: Guo, Zhen, Lucas, P. W., Kurtev, R. G., Borissova, J., Elbakyan, V., Morris, C., Bayo, A., Smith, L., Garatti, A. Caratti o, Peña, C. Contreras, Minniti, D., Jose, J., Ashraf, M., Alonso-García, J., Miller, N., Muthu, H. D. S.

During the pre-main-sequence evolution, Young Stellar Objects (YSOs) assemble most of their mass during the episodic accretion process. The rarely seen FUOr-type events (FUOrs) are valuable laboratories to investigate the outbursting nature of YSOs.

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflation'' problem could have an impact on both stellar and exoplanetary sc
