Twenty-year monitoring of the surface magnetic fields of chemically peculiar stars
M. Giarrusso, M. Cecconi, R. Cosentino +5
Magnetic chemically peculiar stars of the main sequence can present rotational periods as long as many decades. Here we report the results of an observational campaign started in 2…
A HARPS-N mass for the elusive Kepler-37d: a case study in disentangling stellar activity and planetary signals
V. M. Rajpaul, L. A. Buchhave, G. Lacedelli +22
To date, only 18 exoplanets with radial velocity (RV) semi-amplitudes m/s have had their masses directly constrained. The biggest obstacle to RV detection of such exoplanets i…
Wolf 503 b: Characterization of a Sub-Neptune Orbiting a Metal-Poor K Dwarf
Alex S. Polanski, Ian J. M. Crossfield, Jennifer A. Burt +35
Using radial velocity measurements from four instruments, we report the mass and density of a sub-Neptune orbiting the quiet K-dwarf Wolf 503 (HIP…
Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network
T. W. Milbourne, D. F. Phillips, N. Langellier +21
State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
Five carbon- and nitrogen-bearing species in a hot giant planet's atmosphere
Paolo Giacobbe, Matteo Brogi, Siddharth Gandhi +40
The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot Jupiters) have been probed for nearly two decades. They allow us to investigate the chemical a…
The GAPS programme at TNG XXX. Atmospheric Rossiter-McLaughlin effect and atmospheric dynamics of KELT-20b
M. Rainer, F. Borsa, L. Pino +30
Transiting ultra-hot Jupiters are ideal candidates to study the exoplanet atmospheres and their dynamics, particularly by means of high-resolution, high signal-to-noise ratio spect…
Optical and ultraviolet pulsed emission from an accreting millisecond pulsar
F. Ambrosino, A. Miraval Zanon, A. Papitto +28
Millisecond spinning, low magnetic field neutron stars are believed to attain their fast rotation in a 0.1-1 Gyr-long phase during which they accrete matter endowed with angular mo…
The GAPS Programme at TNG. XXIX. No detection of reflected light from 51 Peg b using optical high-resolution spectroscopy
G. Scandariato, F. Borsa, D. Sicilia +44
The analysis of exoplanetary atmospheres by means of high-resolution spectroscopy is an expanding research field which provides information on chemical composition, thermal structu…
Towards new servo control algorithms at the TNG telescope
P. Schipani, M. Gonzalez, F. Perrotta +5
The servo control algorithms of the TNG, developed in the nineties, have been working for more than 20 years with no major updates. The original hardware was based on a VME-bus bas…
