A giant planet imaged in the disk of the young star Beta Pictoris
A. -M. Lagrange, M. Bonnefoy, G. Chauvin +8
Here we show that the ~10 Myr Beta Pictoris system hosts a massive giant planet, Beta Pictoris b, located 8 to 15 AU from the star. This result confirms that gas giant planets form…
JWST Imaging of the Closest Globular Clusters -- I. Possible Infrared Excess Among White Dwarfs in NGC 6397
L. R. Bedin, D. Nardiello, M. Salaris +9
We present James Webb Space Telescope observations of the globular cluster NGC 6397 and use them to extend to infrared wavelengths the characterization of the cluster's entire whit…
Imaging low-mass planets within the habitable zone of α Centauri
K. Wagner, A. Boehle, P. Pathak +39
Giant exoplanets on wide orbits have been directly imaged around young stars. If the thermal background in the mid-infrared can be mitigated, then exoplanets with lower masses can…
JWST imaging of omega Centauri: II. Evidence for a split white dwarf cooling sequence in the near-infrared
M. Scalco, M. Salaris, L. R. Bedin +11
We present a detailed analysis of the white dwarf cooling sequence (WD CS) in omega Centauri based on combined Hubble Space Telescope (HST) and JWST observations. Our analysis conf…
LBT transmission spectroscopy of HAT-P-12b: confirmation of a cloudy atmosphere with no significant alkali features
F. Yan, N. Espinoza, K. Molaverdikhani +10
The hot sub-Saturn-mass exoplanet HAT-P-12b is an ideal target for transmission spectroscopy because of its inflated radius. We observed one transit of the planet with the multi-ob…
The HST Large Programme on NGC 6752. III. Detection of the Peak of the White Dwarf Luminosity Function
L. R. Bedin, M. Salaris, J. Anderson +10
We report on the white dwarf cooling sequence of the old globular cluster NGC 6752, which is chemically complex and hosts a blue horizontal branch. This is one of the last globular…
