Asteroseismic modelling of solar-type stars: A deeper look at the treatment of initial helium abundance
Benard Nsamba, Nuno Moedas, Tiago L. Campante +7
Detailed understanding of stellar physics is essential towards a robust determination of stellar properties (e.g. radius, mass, and age). Among the vital input physics used in the…
Temporal evolution of short-lived penumbral microjets
A. Siu-Tapia, L. R. Bellot Rubio, D. Orozco Suárez +1
Context. Penumbral microjets are elongated jet-like brightenings observed in the chromosphere above sunspot penumbrae. They are transient events that last from a few seconds to sev…
Transfer Learning in Spatial-Temporal Forecasting of the Solar Magnetic Field
Eurico Covas
Machine learning techniques have been widely used in attempts to forecast several solar datasets. Most of these approaches employ supervised machine learning algorithms which are,…
Spitzer Microlensing parallax reveals two isolated stars in the Galactic bulge
Weicheng Zang, Yossi Shvartzvald, Tianshu Wang +90
We report the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign. The ground-based observations yield the detection of finite-sour…
OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing
Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102
We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…
Neural Network Forecast of the Sunspot Butterfly Diagram
Eurico Covas, Nuno Peixinho, Joao Fernandes
Using neural networks as a prediction method, we attempt to demonstrate that forecasting of the Sun's sunspot time series can be extended to the spatial-temporal case. We employ th…
Many new variable stars discovered in the core of the globular cluster NGC 6715 (M54) with EMCCD observations
R. Figuera Jaimes, D. M. Bramich, N. Kains +38
We show the benefits of using Electron-Multiplying CCDs and the shift-and-add technique as a tool to minimise the effects of the atmospheric turbulence such as blending between sta…
Mass Measurements of Isolated Objects from Space-based Microlensing
Wei Zhu, S. Calchi Novati, A. Gould +78
We report on the mass and distance measurements of two single-lens events from the 2015 \emph{Spitzer} microlensing campaign. With both finite-source effect and microlens parallax…
