Prime Focus Spectrograph on the Subaru Telescope: Overview of Science Operations
Masayuki Tanaka, Akira Arai, Wanqiu He +30
The paper presents the science operation framework for Prime Focus Spectrograph (PFS or 'Onohi'ula in its Hawaiian name) installed at the 8.2m Subaru Telescope on the summit of Mau…
gr8stars II : judgement day for spectroscopic parameter model systematics
Alix Violet Freckelton, Annelies Mortier, Megan Bedell +18
Many areas of astrophysics, including exoplanetary studies, rely on precise and accurate stellar parameters. This demands that uncertainties on these parameters truly reflect all b…
TIC-65910228 b / NGTS-38 b, a 180 day transiting warm super-Jupiter
Toby Rodel, Solène Ulmer-Moll, Samuel Gill +63
We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of R and a mass of M on a long-…
The RoPES project with HARPS and HARPS-N III. Two candidate planets orbiting the G-type star HD 161098
N. Nari, A. Suárez Mascareño, J. I. González Hernández +9
Context. The development of refined instruments and techniques for a detailed analysis of the radial velocities (RVs) of stars other than the Sun allows the presence of planetary s…
NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period
Pierrot Lamontagne, Drew Weisserman, Charles Cadieux +148
We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; pc), based on new high-precision radial velocity (RV) observa…
The RoPES project with HARPS and HARPS-N II. A third planet in the multi-planet system HD 176986
N. Nari, A. Suárez Mascareño, J. I. González Hernández +7
Earth-like planets orbiting in the habitable zone of K- to G-type stars create an RV effect in amplitude of less than 1 \si{\meter\per\second} and have orbital periods of hundreds…
