A PSF-based Approach to TESS High quality data Of Stellar clusters (PATHOS) -- I. Search for exoplanets and variable stars in the field of 47 Tuc
D. Nardiello, L. Borsato, G. Piotto +9
The TESS mission will survey ~85 % of the sky, giving us the opportunity of extracting high-precision light curves of millions of stars, including stellar cluster members. In this…
Radial velocity confirmation of K2-100b: a young, highly irradiated, and low density transiting hot Neptune
O. Barragán, S. Aigrain, D. Kubyshkina +37
We present a detailed analysis of HARPS-N radial velocity observations of K2-100, a young and active star in the Praesepe cluster, which hosts a transiting planet with a period of…
Imprints of Evolution on the Internal Kinematics of Globular Clusters
Laura L. Watkins, Roeland P. van der Marel, Andrea Bellini +2
Globular clusters are collisional systems, meaning that the stars inside them interact on timescales much shorter than the age of the Universe. These frequent interactions transfer…
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…
Spectral Energy Distribution of Blue Stragglers in the core of 47 Tucanae
S. Raso, C. Pallanca, F. R. Ferraro +8
We have constructed the Spectral Energy Distributions (SEDs) of a sample of Blue Straggler Stars (BSSs) in the core of the globular cluster 47 Tucanae, taking advantage of the larg…
Astro2020 Science White Paper: The Local Relics of of Supermassive Black Hole Seeds
Jenny E Greene, Aaron Barth, Andrea Bellini +18
We have compelling evidence for stellar-mass black holes (BHs) of ~5-80 M_sun that form through the death of massive stars. We also have compelling evidence for so-called supermass…
