In the last years, a substantial change has occurred concerning previous concepts accepted for theJurassic tectonics in the area comprehended between the Patagonian and Central Andes. The previoushypothesis conceived a r...

"Education, in and of itself, is neither irrelevant nor outmoded. However, the current need to educate a planetary citizenry under conditions relevant to the living context of our planet is palpable. A new education para...

Environmental factors such as air pollution, weather events, and ambient toxins are major contributors to human disease, with disproportionate impacts on vulnerable populations. In Puerto Rico, chronic exposure to air po...

Introduction According to modern scholars (N. Maslova, B. Astafiev), one of the important reasons for the global planetary crisis, including modern educational system in particular, is violation of the conformity of natu...

Context. Infrared emission from polycyclic aromatic hydrocarbons (PAHs) plays a major role in determining the charge balance of their host environments that include photodissociation regions (PDRs) in galaxies, planetary...

La emergencia climática mundial es un hecho innegable que requiere del máximo esfuerzo para adaptarse y mitigar este efecto planetario. Las leyes y los marcos normativos son elementos que permiten accionar en este sent...

"Systemic Innovation is a field of praxis that is rapidly taking shape as a key driver in R&D initiatives focused on integral sustainability the world over. This field curates the exploration of socio-technical systems d...

The aim of this paper is to contribute to the characterization of the general properties of the Long Period Comets (LPCs) family, and in particular to report on the dust environment of comet C/2009 P1 (Garradd).The comet...

This study examines lunar regolith space weathering as a function of wavelength, terrain type, and latitude using multiple datasets to quantify global and regional trends in surface reflectance and emission. Distinguishi...

There are more than 3000 confirmed and probably known Galactic planetary nebulae (PNe), but central star spectroscopic information is available for only 13% of them. Aims. We have undertaken a spectroscopic survey of the...

Planetary nebulae (PNe) are pivotal for advancing our knowledge of stellar evolution and galactic chemical enrichment. Recentprogress in surveys and data analysis has revolutionized PN research, leading to the discovery ...

Knowledge of and the ability to predict lifting condensation levels (LCL) is important ingredient in weather predictions, cloud formation, planetary albedo and Earth’s energy balance. It is also essential topic in avia...

Context. Asteroseismology has become a powerful diagnostic tool in stellar astrophysics, offering unprecedented insights into the internal structures and dynamics of stars. Through the analysis of stellar oscillation mod...

ABSTRACT In this study, the erosion of the nocturnal boundary layer (NBL) was analyzed in the central Amazon during the dry season of 2014, using data from the GoAmazon 2014/5 Project and high-resolution model outputs (P...

Context. The localized formation of planetesimals can be triggered with the help of streaming instability when the local pebble density is high. This can happen at various locations in the disk leading to the formation o...

Humanity is on a deeply unsustainable trajectory. We are exceeding planetary boundaries and unlikely to meet many international sustainable development goals and global environmental targets. Until recently, there was no...

Context. Astronomical environments are governed by a complex interplay of physical processes, including gravitational dynamics, radiative transfer, stellar evolution, chemistry, and hydrodynamics. These processes span a ...

Context. JWST observations of the Orion Bar have revealed rich and diverse polycyclic aromatic hydrocarbon (PAH) emission. These observations allow for the first time a comprehensive characterisation of the charge state ...

Context: Binary systems with similar components are ideal laboratories that allow several physical processes to be tested, such as the possible chemical pattern imprinted by the planet formation process. Aims. We explore...

Context. The search for extrasolar planets around the nearest M dwarfs is a crucial step toward identifying the nearest Earth-like planets. One of the main challenges in this search is that M dwarfs can be magnetically a...

Using Spitzer photometry at 4.5 microns, we search for rings and satellites around the long period transiting planet CoRoT-9b. We observed two transits in 2010 and 2011. From their non-detection, we derive upper limits o...

Exoplanet surveys have shown that systems with multiple low-mass planets on compact orbits are common. Except for a few cases, however, the masses of these planets are generally unknown. At the very end of the main seque...

We revise the model for the origin of the HD 45364 exoplanetary system proposed by Rein et al. (2010, A&A, 510, A4), which is currently known to host two planets close to the 3/2 mean-motion resonance (MMR). We show t...

Context. Co-orbital objects, also known as Trojans, are celestial bodies that share a 1:1 mean motion resonance orbit with a planet. Many planets in our Solar System hold Trojans, yet none has been confirmed in exoplanet...
