Radial velocity follow up of HD 307842
We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD307842 (TOI-784). The planet has a period of 2.8days, and the radial... -
Unistellar Exoplanet Campaign
This paper presents early results from and prospects for exoplanet science using a citizen science private/public partnership observer network managed by the SETI Institute in... -
Stellar obliquities in exoplanetary systems
The rotation of a star and the revolutions of its planets are not necessarily aligned. This article reviews the measurement techniques, key findings, and theoretical... -
RV and LC of 8 M dwarf stars with planets
Exoplanets smaller than Neptune are common around red dwarf stars (M dwarfs), with those that transit their host star constituting the bulk of known temperate worlds amenable... -
GJ 3512 radial velocity and light curves
Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion theory of planet... -
Masses and RV of exoplanets
Being one of the most fundamental physical parameter of astronomical objects, mass plays a vital role in the study of exoplanets, including their temperature structure, chemical... -
TTVs & linear ephemerides of Kepler exoplanets
We determined new linear ephemerides of transiting exoplanets using long-cadence de-trended data from quarters Q1 to Q17 of Kepler mission. We analysed TTV diagrams of 2098... -
Spin-orbit connection of exoplanets
Star-planet interactions play, among other things, a crucial role in planetary orbital configurations by circularizing orbits, aligning the star and planet spin and... -
70 cool giant exoplanets
Exomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70... -
nu2 Lupi CHEOPS light curves
Exoplanets transiting bright nearby stars are key objects for advancing our knowledge of planetary formation and evolution. The wealth of photons from the host star gives... -
EPIC 228801451 RV and activity indices
Earth, Venus, Mars and some extrasolar terrestrial planets1 have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. At... -
8 UMi radial velocity curve
When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around... -
Properties of exoplanet host stars
Planet formation is generally described in terms of a system containing the host star and a protoplanetary disk, of which the internal properties (for example, mass and... -
WDJ0914+1914 X-Shooter spectrum
The detection of a dust disk around the white dwarf star G29-38 and transits from debris orbiting the white dwarf WD 1145+017 confirmed that the photospheric trace metals found... -
(Sub)Stellar companions of exoplanet hosts
We present the latest results of an ongoing multiplicity survey of exoplanet hosts, which was initiated at the Astrophysical Institute and University Observatory Jena, using... -
Transit KELT-11b observed by CHEOPS
The CHaracterising ExOPlanet Satellite (CHEOPS) was selected on October 19, 2012, as the first small mission (S-mission) in the ESA Science Programme and successfully launched... -
WASP-127 b LCs, WASP-96 b transmission spectra
We present TransitFit, a package designed to fit exoplanetary transit light-curves. TransitFit offers multi-epoch, multi-wavelength fitting of multi-telescope transit data.... -
A super-Earth planet in the WASP-84 system
Hot Jupiters have been perceived as loners devoid of planetary companions in close orbital proximity. However, recent discoveries based on space-borne precise photometry have... -
HD 15906 CHEOPS PIPE and WASP lightcurves
We report the discovery of two warm sub-Neptunes transiting the bright (G=9.5mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet... -
HIP 9618 light and radial velocity curves
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright (G=9.0mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of 3.9+/-0.044...
