Higher resolution optical spectra of galaxies reveal outflow signatures unresolved by the SDSS
B. Hagedorn, C. Cicone, C. Vignali +5
Galactic outflows are predicted to be ubiquitous in low-mass galaxies, but observational evidence is lacking. Both a low signal-to-noise and a low spectral resolution can severely…
The GAPS programme at TNG LXXI. A sub-Neptune suitable for atmospheric characterization in a multiplanet and mutually inclined system orbiting the bright K dwarf TOI-5789 (HIP 99452)
A. S. Bonomo, L. Naponiello, A. Sozzetti +37
Sub-Neptunes with planetary radii of are the most common planets around solar-type stars in short-period ( d) orbits. It is still unclear, howe…
The GAPS Programme at the TNG: LXX. TOI-5734b: A hot sub-Neptune orbiting a relatively young K dwarf with an Earth-like density
S. Filomeno, T. Trifonov, M. Damasso +40
Increasing interest in young exoplanets is leading to a growing effort to understand the formation and evolutionary processes responsible for their different architectures. One int…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design
Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44
Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…
TESS and HARPS-N unveil two planets transiting TOI-1453. A super-Earth and one of the lowest mass sub-Neptunes
M. Stalport, A. Mortier, M. Cretignier +37
We report on the validation and characterisation of two transiting planets around TOI-1453, a K-dwarf star in the TESS northern continuous viewing zone. In addition to the TESS dat…
