HD219666b: A hot-Neptune from TESS Sector 1
M. Esposito, D. J. Armstrong, D. Gandolfi +73
We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (Mstar = 0.92 +/- 0.03 MSun, Rstar = 1.03 +/- 0.03…
The impact of spiral density waves on the star formation distribution: a view from core-collapse supernovae
A. G. Karapetyan, A. A. Hakobyan, L. V. Barkhudaryan +4
We present an analysis of the impact of spiral density waves (DWs) on the radial and surface density distributions of core-collapse (CC) supernovae (SNe) in host galaxies with diff…
SWEET-Cat updated. New homogenous spectroscopic parameters
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14
Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
The AMBRE Project: searching for the closest solar siblings
V. Adibekyan, P. de Laverny, A. Recio-Blanco +7
Finding solar siblings, that is, stars that formed in the same cluster as the Sun, will yield information about the conditions at the Sun's birthplace. We search for solar sibling…
K2-265 b: A Transiting Rocky Super-Earth
K. W. F. Lam, A. Santerne, S. G. Sousa +34
We report the discovery of the super-Earth K2-265 b detected with K2 photometry. The planet orbits a bright (V_mag = 11.1) star of spectral type G8V with a period of 2.37 days. We…
The impact of spiral density waves on the distribution of Supernovae
A. G. Karapetyan, A. A. Hakobyan, L. V. Barkhudaryan +4
We present an analysis of the impact of spiral density waves (DWs) on the radial and surface density distributions of supernovae (SNe) in host galaxies with different arm classes.…
Planets around evolved intermediate-mass stars in open clusters II. Are there really planets around IC4651No9122, NGC2423No3 and NGC4349No127?
E. Delgado Mena, C. Lovis, N. C. Santos +10
(shorter version)The aim of this work is to search for planets around intermediate-mass stars in open clusters by using RV data obtained with HARPS from an extensive survey with mo…
Chemical abundances of neutron capture elements in exoplanet-hosting stars
E. Delgado Mena, V. Zh. Adibekyan, P. Figueira +7
To understand the formation and composition of planetary systems it is important to study their host stars composition since both are formed in the same stellar nebula. In this wor…
The Gaia-ESO Survey: the origin and evolution of s-process elements
L. Magrini, L. Spina, S. Randich +45
Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations, giving important constraints to stell…
The Gaia-ESO Survey: properties of newly discovered Li-rich giants
R. Smiljanic, E. Franciosini, A. Bragaglia +41
We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with evolutionary stage confirmed by CoRoT data. Atmospheric parameter…
An Earth-sized exoplanet with a Mercury-like composition
A. Santerne, B. Brugger, D. J. Armstrong +43
The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…
The Gaia-ESO Survey: Evidence of atomic diffusion in M67?
C. Bertelli Motta, A. Pasquali, J. Richer +37
Investigating the chemical homogeneity of stars born from the same molecular cloud at virtually the same time is very important for our understanding of the chemical enrichment of…
Estimating stellar birth radii and the time evolution of the Milky Way's ISM metallicity gradient
I. Minchev, F. Anders, A. Recio-Blanco +14
We present a semi-empirical, largely model-independent approach for estimating Galactic birth radii, r_birth, for Milky Way disk stars. The technique relies on the justifiable assu…
The Origins Space Telescope: Towards An Understanding of Temperate Planetary Atmospheres
Jonathan Fortney, Tiffany Kataria, Kevin Stevenson +46
The Origins Space Telescope (OST) is one of four mission concepts currently being studied by NASA in preparation for the Astrophysics 2020 Decadal Survey. With active cooling (~4 K…
Exoplanet Diversity in the Era of Space-based Direct Imaging Missions
Ravi Kopparapu, Eric Hebrard, Rus Belikov +55
This whitepaper discusses the diversity of exoplanets that could be detected by future observations, so that comparative exoplanetology can be performed in the upcoming era of larg…
Exploring Extreme Space Weather Factors of Exoplanetary Habitability
V. S. Airapetian, V. Adibekyan, M. Ansdell +46
It is currently unknown how common life is on exoplanets, or how long planets can remain viable for life. To date, we have a superficial notion of habitability, a necessary first s…
C/O vs Mg/Si ratios in solar type stars: The HARPS sample
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Aims. We present a detailed study of the Mg/Si and C/O ratios and their importance in determining the mineralogy of planetary companions. Methods. Using 499 solar-like stars from t…
