Observing the changing surface structures of the active K giant sigma Gem with SONG

H. Korhonen, R. M. Roettenbacher, S. Gu +6

Aims: We aim to study the spot evolution and differential rotation in the magnetically active cool K-type giant star sigma Gem from broadband photometry and continuous spectroscopi…

Vacuum ultraviolet photoabsorption spectroscopy of space-related ices: Formation and destruction of solid carbonic acid upon 1~keV electron irradiation

S. Ioppolo, Z. Kanuchová, R. L. James +7

Carbonic acid (H2CO3) is a weak acid relevant to astrobiology which, to date, remains undetected in space. Experimental work has shown that the beta-polymorph of H2CO3 forms under…

Age-metallicity dependent stellar kinematics of the Milky Way disc from LAMOST and Gaia

Yaqian Wu, Maosheng Xiang, Yuqin Chen +5

We investigate the stellar kinematics of the Galactic disc in 7 13\,kpc using a sample of 118\,945 red giant branch (RGB) stars from LAMOST and Gaia. We characterize th…

Mode Angular Degree Identification in Subgiant Stars with Convolutional Neural Networks based on Power Spectrum

Minghao Du, Shaolan Bi, Xianfei Zhang +3

Identifying the angular degrees of oscillation modes is essential for asteroseismology and depends on visual tagging before fitting power spectra in a so-called peakbagging ana…

Inverse analysis of asteroseismic data: a review

Earl P. Bellinger, Sarbani Basu, Saskia Hekker

Asteroseismology has emerged as the best way to characterize the global and internal properties of nearby stars. Often, this characterization is achieved by fitting stellar evoluti…

SOXS: Effects on optical performances due to gravity flexures, temperature variations, and subsystems alignment

Ricardo Zanmar Sanchez, Matteo Aliverti, Matteo Munari +43

SOXS (Son Of X-Shooter) is the new medium resolution wide-band spectrograph to be installed at the 3.6m New Technology Telescope (NTT) in La Silla. SOXS will offer simultaneous wav…
