Aims: We aim to observe the transits and occultations of WASP-33b, which orbits a rapidly-rotating $\delta$ Scuti pulsator, with the goal of measuring the orbital obliquity via the gravity-darkening effect, and constraining the geometric albedo via t

Effects of diameter polydispersity and small-range interactions on the structure of biocompatible colloidal nanoparticles

Autor: Kanzaki, Aimê Gomes da Mata, Cassiano, Tiago de Sousa Araújo, Valeriano, João, Paula, Fabio Luis de Oliveira, Castro, Leonardo Luiz e

The particles of synthetic colloids are usually treated with chemical techniques to prevent the loss of colloidal stability caused by van der Waals and magnetic dipolar attractive interactions. However, understanding the counterbalance between the at

Integrating Positionality Statements in Empirical Software Engineering Research

Autor: de Sousa, Breno Felix, Santos, Ronnie de Souza, Gama, Kiev

Positionality statements are a reflective practice established in fields such as social sciences, where they enhance transparency, reflexivity, and ethical integrity by acknowledging how researchers identities, experiences, and perspectives may shape

We present the discovery of two mini Neptunes near a 2:1 orbital resonance configuration orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest some possible formation and evolution scenarios. Using CHEOPS, TESS,
