A Dearth of Close-in Stellar Companions to M-dwarf TESS Objects of Interest
- Physics, GeologyThe Astronomical Journal
- 2022
TESS has proven to be a powerful resource for finding planets, including those that orbit the most prevalent stars in our galaxy: M dwarfs. Identification of stellar companions (both bound and…
Assessment of [Fe/H] determinations for FGK stars in spectroscopic surveys
- GeologyAstronomy & Astrophysics
- 2022
Context. The iron abundance [Fe/H] in the atmosphere of FGK-type stars is crucial in stellar and galactic physics. The number of stars with a measured value of [Fe/H] is considerably increasing…
CZEV502 – AN M DWARF NEAR THE LEO TRIPLET WITH VERY STRONG FLARES
- PhysicsRevista Mexicana de Astronomía y Astrofísica
- 2022
Discovery of flares in the M dwarf CzeV502 and our follow-up results are presented. We classify it as a dMe eruptive variable of UV Ceti type due to the X-ray activity, measured B − V of 1.5 mag, Hα;…
Chemistry of nebulae around binary post-AGB stars: A molecular survey of mm-wave lines
- PhysicsAstronomy & Astrophysics
- 2022
Context. There is a class of binary post-asymptotic giant branch (post-AGB) stars that exhibit remarkable near-infrared (NIR) excess. Such stars are surrounded by Keplerian or quasi-Keplerian disks,…
Coincidence between morphology and star-formation activity through cosmic time: the impact of the bulge growth
- Physics
- 2022
The origin of the quenching in galaxies is still highly debated. Different scenarios and processes are proposed. We use multi band (400 − 1600 nm) bulge-disc decompositions of massive galaxies in the…
Compositional Mapping of Europa Using MCMC Modeling of Near-IR VLT/SPHERE and Galileo/NIMS Observations
- Physics, Environmental ScienceThe Planetary Science Journal
- 2022
We present maps of surface composition of Europa’s anti-Jovian hemisphere acquired using high spatial resolution IFU multispectral data from the SPHERE instrument on the Very Large Telescope…
Deep ASKAP EMU Survey of the GAMA23 field: Properties of radio sources
- Physics
- 2022
Wepresent theAustralian SquareKilometreArray Pathfinder (ASKAP) observations of theGalaxy andMassAssembly (GAMA)23h field. The survey was carried out at 887.5 MHz and covers a ∼83 square degree…
Dissecting the Different Components of the Modest Accretion Bursts of the Very Young Protostar HOPS 373
- PhysicsThe Astrophysical Journal
- 2022
Observed changes in protostellar brightness can be complicated to interpret. In our James Clerk Maxwell Telescope (JCMT) Transient Monitoring Survey, we discovered that a young binary protostar, HOPS…
Impact of very massive stars on the chemical evolution of extremely metal-poor galaxies
- PhysicsAstronomy & Astrophysics
- 2022
Context. In recent observations of extremely metal-poor low-mass starburst galaxies, almost solar Fe / O ratios are reported, despite N / O ratios consistent with the low metallicity. Aims. We…
