Bridging the UV Gap: The HST Ultraviolet Foundation for Star Formation Science in the Era of Roman, Euclid, and HWO
F. Z. Majidi, A. Bayo, K. Biazzo +4
As we enter the 2030s, the astronomical landscape will be dominated by large-scale infrared (IR) and optical surveys led by JWST, Euclid, and the Nancy Grace Roman Space Telescope.…
ASASSN-24fw: An 8-month long, 4.1 mag, optically achromatic and polarized dimming event
R. Forés-Toribio, B. JoHantgen, C. S. Kochanek +20
We discuss ASASSN-24fw, a 13th-magnitude star that optically faded by mag starting in September 2024 after over a decade of quiescence in ASAS-SN. The dimmimg…
RedDots: Planetary masses in the GJ1061 system from planet-planet interaction
S. Dreizler, S. V. Jeffers, F. Liebing +8
GJ1061 is a very nearby M star hosting three low-mass temperate planets detected from radial velocity variations. The close to 4:2:1 period commensurability of the planets, the ava…
Water-Cooled (sub)-Neptunes Get Better Gas Mileage
Tatsuya Yoshida, Eric Gaidos
The demographics of sub-Jovian planets around low-mass stars is dominated by populations of ``sub-Neptunes" and ``super-Earths", distinguished by the presence or absence of envelop…
TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet
K. Barkaoui, J. Korth, E. Gaidos +119
TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
