PLATOSpec: a precise spectrograph in support of space missions

P. Kabáth, M. Skarka, A. Hatzes +42

The upcoming space missions that will characterize exoplanets, such as PLATO and Ariel, will collect huge amounts of data that will need to be complemented with ground-based observ…

Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b

S. Ulmer-Moll, S. Gill, R. Brahm +64

Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…

Optical ray tracing of echelle spectrographs applied to the wavelength solution for precise radial velocities

Marcelo Tala Pinto, Adrian Kaminski, Andreas Quirrenbach +1

We present , a ray tracing software package that computes the path of rays through echelle spectrographs. Our algorithm is based on sequential direct tracing with Se…

A long-period transiting substellar companion in the super-Jupiters to brown dwarfs mass regime and a prototypical warm-Jupiter detected by TESS

Matias I. Jones, Yared Reinarz, Rafael Brahm +48

We report on the confirmation and follow-up characterization of two long-period transiting substellar companions on low-eccentricity orbits around TIC 4672985 and TOI-2529, whose t…

Two long-period transiting exoplanets on eccentric orbits: NGTS-20 b (TOI-5152 b) and TOI-5153 b

S. Ulmer-Moll, M. Lendl, S. Gill +50

Long-period transiting planets provide the opportunity to better understand the formation and evolution of planetary systems. Their atmospheric properties remain largely unaltered…

A new third planet and the dynamical architecture of the HD33142 planetary system

Trifon Trifonov, Anna Wollbold, Martin Kürster +24

Based on recently-taken and archival HARPS, FEROS and HIRES radial velocities (RVs), we present evidence for a new planet orbiting the first ascent red giant star HD33142 (with an…

TARdYS: Design and Prototype of an Exoplanet Hunter for TAO using a R6 Echelle Grating

S. Rukdee, L. Vanzi, C. Schwab +7

One limitation in characterizing exoplanet candidates is the availability of infrared, high-resolution spectrographs. An important factor in the scarcity of high precision IR spect…

NGTS-11 b / TOI-1847 b: A transiting warm Saturn recovered from a TESS single-transit event

Samuel Gill, Peter J. Wheatley, Benjamin F. Cooke +37

We report the discovery of NGTS-11 b (=TOI-1847 b), a transiting Saturn in a 35.46-day orbit around a mid K-type star (Teff=5050 K). We initially identified the system from a singl…

The CARMENES search for exoplanets around M dwarfs. Two temperate Earth-mass planet candidates around Teegarden's Star

M. Zechmeister, S. Dreizler, I. Ribas +182

Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0V), the star shows relatively little…

Precision stellar radial velocity measurements with FIDEOS at the ESO 1-m telescope of La Silla

L. Vanzi, A. Zapata, M. Flores +10

We present results from the commissioning and early science programs of FIDEOS, the new high-resolution echelle spectrograph developed at the Centre of Astro Engineering of Pontifi…
