ESO Staff Publications (2019) ESO Staff Publications (2019) Peer-reviewed publications by ESO scientists The ESO Library maintains the ESO Telescope Bibliography (telbib) and is responsible for providing paper-based statistics. Publications in refereed journals based on ESO data (2019) can be retrieved through telbib: ESO data papers 2019. Access to the database for the years 1996 to present as well as an overview of publication statistics are available via http://telbib.eso.org and from the "Basic ESO Publication Statistics" document. Papers that use data from non-ESO telescopes or observations obtained with hosted telescopes are not included. The list below includes papers that are (co-)authored by ESO authors, with or without use of ESO data. It is ordered alphabetically by first ESO-affiliated author.

We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective temperatures hotter than the Sun, and on the other hand, to explore the Li dip and the evolution of Li at high metallicities. Methods. We present lithium abundances for 353 main sequence stars with and without planets in the Teff range 5900–7200 K. We observed 265 stars of our sample with HARPS spectrograph during different planets search programs. We observed the remaining targets with a variety of high-resolution spectrographs.

    Research in Astronomy and Astrophysics manuscript no. (LATEX: tikhonov˙Dorado.tex; printed on September 15, 2020; 1:01) Distance to the Dorado galaxy group N.A. Tikhonov1, O.A. Galazutdinova1 Special Astrophysical Observatory, Nizhnij Arkhyz, Karachai-Cherkessian Republic, Russia 369167; [email protected] Abstract Based on the archival images of the Hubble Space Telescope, stellar photometry of the brightest galaxies of the Dorado group:NGC 1433, NGC1533,NGC1566and NGC1672 was carried out. Red giants were found on the obtained CM diagrams and distances to the galaxies were measured using the TRGB method. The obtained values: 14.2±1.2, 15.1±0.9, 14.9 ± 1.0 and 15.9 ± 0.9 Mpc, show that all the named galaxies are located approximately at the same distances and form a scattered group with an average distance D = 15.0 Mpc. It was found that blue and red supergiants are visible in the hydrogen arm between the galaxies NGC1533 and IC2038, and form a ring structure in the lenticular galaxy NGC1533, at a distance of 3.6 kpc from the center. The high metallicity of these stars (Z = 0.02) indicates their origin from NGC1533 gas.

    UNIVERSIDADE FEDERAL DO RIO GRANDE DO SUL INSTITUTO DE F´ISICA DEPARTAMENTO DE ASTRONOMIA Self-consistent nebular emission and stellar population analysis of jellyfish galaxies Gabriel Maciel Azevedo Trabalho de Conclus~ao de Curso ap- resentado `aComi¸c~aode Gradua¸c~aoem F´ısica do Instituto de F´ısica da Univer- sidade Federal do Rio Grande do Sul sob orienta¸c~aoda Prof. Dr. Ana Leonor Chies Santiago Santos e do Prof. Dr. Rog´erio Riffel, como parte dos requisitos para a obten¸c~aodo grau de Bacharel em F´ısica- ^enfaseem Astrof´ısica. Porto Alegre, RS, Brasil May, 2021 \As flores brotam e morrem, as estrelas brilham, mas um dia se apagar~ao.Tudo morre, a Terra, o Sol, a Via L´actea, e at´emesmo todo esse universo n~ao´e exce¸c~ao.. Comparado a isso, a vida do homem ´et~aobreve e fugidia quanto um piscar de olhos. Nesse curto instante, os homens nascem, riem, choram, lutam, sofrem, festejam, lamentam, odeiam pessoas e amam outras. Tudo ´etransit´orio,e em seguida todos caem no sono eterno chamado morte." Masami Kurumada (Shaka, Cavaleiros do Zod´ıaco,ep 124) Agradecimentos Agrade¸co`aminha fam´ıliapor todo apoio e carinho ao longo desses anos, e em especial aos meus pais por sempre terem me incentivado a me dedicar aos estudos e continuamente trabalhado para me prover educa¸c~aode qualidade. Agrade¸co`aminha namorada Caroline, por ter me acompanhado, me divertido e me ajudado durante esses ´ultimossemestres de gradua¸c~ao. Agrade¸coaos meus amigos antigos por alegrarem meus dias ao longo de tantos anos, e em especial ao Eduardo, que me incentivou a seguir com minha escolha de profiss˜ao.

    Monster image of the Fornax Galaxy Cluster 25 October 2017 telescope technology to observe the finer details of NGC 1316's unusual structure through a combination of imaging and modelling. The mergers that formed NGC 1316 led to an influx of gas, which fuels an exotic astrophysical object at its centre: a supermassive black hole with a mass roughly 150 million times that of the Sun. As it accretes mass from its surroundings, this cosmic monster produces immensely powerful jets of high- energy particles , that in turn give rise to the Credit: ESO characteristic lobes of emission seen at radio wavelengths, making NGC 1316 the fourth- brightest radio source in the sky. Countless galaxies vie for attention in this monster NGC 1316 has also been host to four recorded type image of the Fornax Galaxy Cluster, some Ia supernovae, which are vitally important appearing only as pinpricks of light while others astrophysical events for astronomers. Since type Ia dominate the foreground. One of these is the supernovae have a very clearly defined brightness, lenticular galaxy NGC 1316. The turbulent past of they can be used to measure the distance to the this much-studied galaxy has left it with a delicate host galaxy; in this case, 60 million light-years. structure of loops, arcs and rings that astronomers These "standard candles" are much sought-after by have now imaged in greater detail than ever before astronomers, as they are an excellent tool to with the VLT Survey Telescope.
