XUV emission of the young planet-hosting star V1298\,Tau from coordinated observations with XMM-Newton and HST
A. Maggio, I. Pillitteri, C. Argiroffi +16
Atmospheric mass loss plays a major role in the evolution of exoplanets. This process is driven by the stellar high-energy irradiation, especially in the first hundreds of millions…
Transit timing variation analysis of the low-mass brown dwarf KELT-1 b
Ö. Baştürk, J. Southworth, S. Yalçınkaya +8
We investigate whether there is a variation in the orbital period of the short-period brown dwarf-mass KELT-1\,b, which is one of the best candidates to observe orbital decay. We o…
The GAPS Programme with HARPS-N at TNG. XXXV. Fundamental properties of transiting exoplanet host stars
K. Biazzo, V. D'Orazi, S. Desidera +38
Exoplanetary properties depend on stellar properties: to know the planet with accuracy and precision it is necessary to know the star as accurately and precisely as possible. Our i…
An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing
Kailash C. Sahu, Jay Anderson, Stefano Casertano +90
We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…
Large-scale changes of the cloud coverage in the Indi Ba,Bb system
J. A. Hitchcock, Ch. Helling, A. Scholz +22
We present the results of 14 nights of \textit{I}-band photometric monitoring of the nearby brown dwarf binary, Indi Ba,Bb. Observations were acquired over 2 months, and total…
Spitzer Microlensing parallax reveals two isolated stars in the Galactic bulge
Weicheng Zang, Yossi Shvartzvald, Tianshu Wang +90
We report the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign. The ground-based observations yield the detection of finite-sour…
