Characterisation of the TOI-421 planetary system using CHEOPS, TESS, and archival radial velocity data

A. F. Krenn, D. Kubyshkina, L. Fossati +88

The TOI-421 planetary system contains two sub-Neptune-type planets and is a prime target to study the formation and evolution of planets and their atmospheres. The inner planet is…

OGLE-2017-BLG-0406: Microlens Parallax Reveals Saturn-mass Planet orbiting M-dwarf Host in the Inner Galactic Disk

Yuki Hirao, David P. Bennett, Yoon-Hyun Ryu +93

We report the discovery and analysis of the planetary microlensing event OGLE-2017-BLG-0406, which was observed both from the ground and by the satellite in a solar…

Metals in the Exosphere of the Highly Irradiated Planet WASP-12b

L. Fossati, C. A. Haswell, C. S. Froning +17

We present near-UV transmission spectroscopy of the highly irradiated transiting exoplanet WASP-12b, obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope. Th…

An extreme thermal cycling reliability test of ATLAS ITk Strips barrel modules

A. Tishelman-Charny, A. Affolder, F. Capocasa +17

At the end of Run 3 of the Large Hadron Collider (LHC), the accelerator complex will be upgraded to the High-Luminosity LHC (HL-LHC) in order to increase the total amount of data p…

OGLE-2017-BLG-1434Lb: Eighth q < 1 * 10^-4 Mass-Ratio Microlens Planet Confirms Turnover in Planet Mass-Ratio Function

A. Udalski, Y. -H. Ryu, S. Sajadian +55

We report the discovery of a cold Super-Earth planet (m_p=4.4 +/- 0.5 M_Earth) orbiting a low-mass (M=0.23 +/- 0.03 M_Sun) M dwarf at projected separation a_perp = 1.18 +/- 0.10 AU…

OGLE-2017-BLG-0329L: A Microlensing Binary Characterized with Dramatically Enhanced Precision Using Data from Space-based Observations

C. Han, S. Calchi Novati, A. Udalski +54

Mass measurements of gravitational microlenses require one to determine the microlens parallax $\pie$, but precise $\pie$ measurement, in many cases, is hampered due to the subtlet…

Physical and orbital properties of Beta Pictoris b

M. Bonnefoy, G. -D. Marleau, R. Galicher +13

The intermediate-mass star Beta Pictoris is known to be surrounded by a structured edge-on debris disk within which a gas giant planet was discovered orbiting at 8-10 AU. The physi…

Giant Outer Transiting Exoplanet Mass (GOTEM) Survey.VII. TOI-6041: a multi-planet system including a warm Neptune exhibiting strong TTVs

N. Heidari, A. Alnajjarine, H. P. Osborn +101

We present the characterization of the TOI-6041 system, a bright () G7-type star hosting at least two planets. The inner planet, TOI-6041b, is a warm Neptune wit…

Mapping the in-plane electric field inside irradiated diodes

L. Poley, A. J. Blue, C. Buttar +12

A significant aspect of the Phase-II Upgrade of the ATLAS detector is the replacement of the current Inner Detector with the ATLAS Inner Tracker (ITk). The ATLAS ITk is an all-sili…
