ExoClock Project: An open platform for monitoring the ephemerides of Ariel targets with contributions from the public
Anastasia Kokori, Angelos Tsiaras, Billy Edwards +46
The Ariel mission will observe spectroscopically around 1000 exoplanets to further characterise their atmospheres. For the mission to be as efficient as possible, a good knowledge…
The GAPS Programme at TNG XXVIII -- A pair of hot-Neptunes orbiting the young star TOI-942
Ilaria Carleo, Silvano Desidera, Domenico Nardiello +48
Both young stars and multi-planet systems are primary objects that allow us to study, understand and constrain planetary formation and evolution theories. We validate the physical…
The GAPS Programme at TNG XXVII. Reassessment of a young planetary system with HARPS-N: is the hot Jupiter V830 Tau b really there?
M. Damasso, A. F. Lanza, S. Benatti +41
Detecting and characterising exoworlds around very young stars (age10 Myr) are key aspects of exoplanet demographic studies, especially for understanding the mechanisms and time…
LBT transmission spectroscopy of HAT-P-12b: confirmation of a cloudy atmosphere with no significant alkali features
F. Yan, N. Espinoza, K. Molaverdikhani +10
The hot sub-Saturn-mass exoplanet HAT-P-12b is an ideal target for transmission spectroscopy because of its inflated radius. We observed one transit of the planet with the multi-ob…
Probing the atmosphere of HD189733b with the Na I and K I lines
E. Keles, D. Kitzmann, M. Mallonn +12
High spectral resolution transmission spectroscopy is a powerful tool to characterize exoplanet atmospheres. Especially for hot Jupiters, this technique is highly relevant, due to…
Role of the impact parameter in exoplanet transmission spectroscopy
X. Alexoudi, M. Mallonn, E. Keles +3
Transmission spectroscopy is a promising tool for the atmospheric characterization of transiting exoplanets. Because the planetary signal is faint, discrepancies have been reported…
The GAPS Programme at TNG -- XXV. Stellar atmospheric parameters and chemical composition through GIARPS optical and near-infrared spectra
M. Baratella, V. D'Orazi, K. Biazzo +20
The detailed chemical composition of stars is important in many astrophysical fields, among which the characterisation of exoplanetary systems. Previous studies seem to indicate an…
TESS unveils the optical phase curve of KELT-1b. Thermal emission and ellipsoidal variation from the brown dwarf companion, and activity from the star
C. von Essen, M. Mallonn, A. Piette +8
We present the detection and analysis of the phase curve of KELT-1b at optical wavelengths, analyzing data taken by the Transiting Exoplanet Survey Satellite (TESS). With a mass of…
X-ray irradiation and evaporation of the four young planets around V1298 Tau
K. Poppenhaeger, L. Ketzer, M. Mallonn
Planets around young stars are thought to undergo atmospheric evaporation due to the high magnetic activity of the host stars. Here we report on X-ray observations of V1298 Tau, a…
TESS Data for Asteroseismology: Timing verification
Carolina von Essen, Mikkel N. Lund, Rasmus Handberg +11
The Transiting Exoplanet Survey Satellite (TESS) is NASA's latest space telescope dedicated to the discovery of transiting exoplanets around nearby stars. Besides the main goal of…
Original Research By Young Twinkle Students (ORBYTS): Ephemeris Refinement of Transiting Exoplanets
Billy Edwards, Quentin Changeat, Kai Hou Yip +60
We report follow-up observations of transiting exoplanets that have either large uncertainties (>10 minutes) in their transit times or have not been observed for over three years.…
TESS unveils the phase curve of WASP-33b. Characterization of the planetary atmosphere and the pulsations from the star
C. von Essen, M. Mallonn, C. C. Borre +4
We present the detection and characterization of the full-orbit phase curve and secondary eclipse of the ultra-hot Jupiter WASP-33b at optical wavelengths, along with the pulsation…
HST/STIS transmission spectrum of the ultra-hot Jupiter WASP-76 b confirms the presence of sodium in its atmosphere
C. von Essen, M. Mallonn, S. Hermansen +4
We present an atmospheric transmission spectrum of the ultra-hot Jupiter WASP-76 b by analyzing archival data obtained with the Space Telescope Imaging Spectrograph (STIS) on board…
High-resolution spectroscopy and spectropolarimetry of the total lunar eclipse January 2019
K. G. Strassmeier, I. Ilyin, E. Keles +5
Observations of the Earthshine off the Moon allow for the unique opportunity to measure the large-scale Earth atmosphere. Another opportunity is realized during a total lunar eclip…
Stellar activity consequence on the retrieved transmission spectra through chromatic Rossiter-McLaughlin observations
S. Boldt, M. Oshagh, S. Dreizler +5
Mostly multiband photometric transit observations have been used so far to retrieve broadband transmission spectra of transiting exoplanets in order to study their atmosphere. An a…
