Discovery of an Eccentric Hot Super-Jupiter Leaving the Transiting Geometry of the Early-A-type star TOI-1355

Noriharu Watanabe, Norio Narita, Akihiko Fukui +20

Hot Jupiters orbiting hot stars ( K) are suggested to have experienced high-eccentricity migration, often evidenced by the tendency for misaligned orbits, de…

NGC 1647: A young open cluster with a broad main sequence observed with LAMOST

A. Frasca, M. Qin, J. ALonso-Santiago +4

In this work we present the results of our analysis of medium-resolution LAMOST spectra of candidate members of the cluster NGC 1647 with the aim of determining the stellar paramet…

Discovery of the binary nature of the magnetospheric B-type star Oph A

M. E. Shultz, I. Berry, D. Bohlender +11

The nearby B-type star Oph A was recently identified as a rapidly rotating magnetic B-type star with variable radio and X-ray emission consistent with a magnetospheric origin.…

Super-slowly rotating Ap (ssrAp) stars: Spectroscopic study

G. Mathys, D. L. Holdsworth, M. Giarrusso +3

To gain better understanding of the Ap stars with the longest rotation periods, we obtained high resolution spectra of a sample of super-slowly rotating Ap (ssrAp) star candidates…

Stellar population astrophysics (SPA) with the TNG: Measurement of the He I 10830Å line in the open cluster Stock 2

Mingjie Jian, Xiaoting Fu, Noriyuki Matsunaga +10

The precise measurement of stellar abundances plays a pivotal role in providing constraints on the chemical evolution of the Galaxy. However, before spectral lines can be employed…

Cepheid Metallicity in the Leavitt Law (C- MetaLL) survey: VI: Radial abundance gradients of 29 chemical species in the Milky Way Disk

E. Trentin, G. Catanzaro, V. Ripepi +9

Classical Cepheids (DCEPs) are crucial for calibrating the extragalactic distance ladder, ultimately enabling the determination of the Hubble constant through the PL and PW relatio…
