TOI-4515 b, a “warm Jupiter” with a turbulent story. The study: “The GAPS programme at TNG L. TOI-4515 b: An eccentric warm Jupiter orbiting a 1.2 Gyr-old G-star” of I. Carleo (Instituto de Astrofísica de Canarias) recently appeared on A&A

The study of the orbital parameters of exoplanets can shed light on their past. An important quantity in this context is the eccentricity of elliptical orbits, which is the ratio between the distance of the foci over the major semiaxis. Eccentricity is equal to zero when the ellipse degenerates into a circle or equal to one when it degenerates into

Synthesis of spectra of exoplanetary atmospheres externally irradiated by X/UV radiation. The study: “Signatures of X-ray dominated chemistry in the spectra of exoplanetary atmospheres” of D. Locci (INAF – OAPA) appeared on PSJ

One of the lessons we have learned after two decades of exoplanetary science, primarily from the diversity of exoplanets discovered to date, is that various properties of exoplanets depend on the characteristics and evolution of their parent stars. Specifically, stellar X-ray and UV radiation can impact the chemical and physical properties of planetary atmospheres. While UV radiation is primarily absorbed

Developed a metjod aimed at characterizing spots in active stars. The paper: “The GAPS programme at TNG LII. Spot modeling of V1298 Tau using SpotCCF tool” of C. di Mario (INAF – OAPA) recently appeared on A&A

The Sun regularly exhibits magnetic phenomena, including sunspots and solar flares, which are not only visually appealing but also crucial for in-depth study and understanding. This is because these phenomena arise from large-scale interactions between the solar magnetic field and its plasma. Moreover, they provide valuable insights into the structure of the Sun and its atmosphere.   Almost all other

A planet with elusive properties for V1298 Tau. The paper: “Photometric follow-up of the 20 Myr old multi-planet host star V1298 Tau with CHEOPS and ground-based telescopes” of M. Damasso (INAF-OATo) appeared on A&A

Among the stars known to host more than one planet, V1298 Tau deserves particular attention. This star, located approximately 360 light years away from us, is around 20 million years old and possesses a planetary system with four exoplanets discovered so far. Due to these characteristics, V1298 Tau can offer valuable insights into the planetary formation process and the early

Formation and evolution of the complex planetary system of V1298 Tau, described in the study: “The GAPS programme at TNG. XLVIII. The unusual formation history of V1298 Tau” of D. Turrini (INAF – OATo)

The study of the exoplanets orbiting around young stars (e.g., younger than a few tens of million of years) offer the important opportunity for studying the early evoalutionary phases of those processes that shape the architecture of planetary systems. However, it is quite difficult to detect and study exoplanets around young stars, because of their low number, the complexity of their

A rich and complex planetary system for the star TOI-4010. The paper: “TOI-4010: A System of Three Large Short-period Planets with a Massive Long-period Companion” of M. Kunimoto (MIT) appeared on AJ)

To date (November 2023), we have confirmed the presence of 5539 exoplanets in 4128 planetary systems. These numbers indicate that, in the majority of cases, we have identified one planet per planetary system. This limitation is primarily due to observational constraints, as it remains challenging to detect small exoplanets with long orbital periods (distant from their stars several astronomical units,

On the fequency of sub-neptunians in planetary systems with giant planets. The study: “The GAPS programme at TNG. XLVI. Deep search for low-mass planets in late-dwarf systems hosting cold Jupiters” of M. Pinamonti (INAF – OATo) appeared on A&A

The two giant planets of the Solar System, Jupiter and Saturn, played an important role in shaping the properties and architecture of the inner solar system. This may be a quite general rule. The presence of giant planets, for instance, can be responsible for a less effective migration of solids and gas toward the inner part of planetary systems, inhibiting

A planet and a brown dwarf for TOI-179. The paper: “TOI-179: A young system with a transiting compact Neptune-mass planet and a low-mass companion in outer orbit” of S. Desidera (INAF – OAPd) appeared on A&A

Typically, planets did not form at the distance from their central stars where we observe them today. In fact, during their early evolution, planets migrate from their initial orbit until the system reaches its final configuration. Planetary migration can be induced by several processes: the interaction between the newborn planets and the protoplanetary disk where they formed, the gravitational interaction

Two terrestrial planets discovered in the habitable zone of the star GJ1002. The study: “Two temperate Earth-mass planets orbiting the nearby star GJ1002” of A. Suárez Mascareño (Istituto de Astrofisica de Canarias) appeaed on A&A

The search for terrestrial like exoplanets in the habitable zone of their stars is one of the most significant areas of exoplanetary science. The habitable zone is defined as the region around a given star where rocky planets are within the suitable temperature range to potentially support liquid water on their surfaces. Earth-like planets within habitable zones are therefore the

Five molecular species found in the atmosphere of WASP-69b. The study: “The GAPS Programme at TNG. XXXVIII. Five molecules in the atmosphere of the warm giant planet WASP-69b detected at high spectral resolution” of G. Guilluy (INAF-OATo) recently appeared on A&A

In recent years, advances in instrumentation, knowledge, and observational strategies in the field of exoplanets have allowed for the identification and confirmation of thousands of planets around other stars (exoplanets). Moreover, for the past few years, astronomers have been capable of studying the chemistry and physical properties of the atmospheres of some of these exotic worlds. These studies can also
