Gaia Focused Product Release: Radial velocity time series of long-period variables
Stephan Morgenthaler, Shuangqing Liao
Context. The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocity data planned with Data Release 4, this Focused Product Release (F ...
Les Ulis Cedex A2023LensWatch. I. Resolved HST Observations and Constraints on the Strongly Lensed Type Ia Supernova 2022qmx ("SN Zwicky")
Frédéric Courbin, Adriano Agnello
Supernovae (SNe) that have been multiply imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools and methodologies needed as the sample of lensed SNe increases by orders of ...
IOP Publishing Ltd2023Columnlike free-interface flows: symmetry breaking and linear instability
This thesis is dedicated to the analysis of a subclass of interfacial flows, columnlike free-interface flows, from two view angles: (i) the symmetry breaking under geometry-induced or external forces, (ii) their stability against infinitesimal disturbances ...
EPFL2023Search for relativistic fractionally charged particles in space
Jian Wang, Yi Zhang, Jennifer Maria Frieden, Chiara Perrina, Zhirui Xu, Siyuan Wang, Songmei Wu, Junqiu Liu, Johan Juul Chang, Jie Chen, Cheng Zhao, Wei Li, Yong Yang, Yi Wang, Hao Liu, Xiao Wang, Shuai Liu, Wenyu Zhang, Xuan Li, Yao Zhang, Ming Gao, Arshia Ruina, Andrii Kotenko
More than a century after the performance of the oil drop experiment, the possible existence of fractionally charged particles (FCPs) still remains unsettled. The search for FCPs is crucial for some extensions of the Standard Model in particle physics. Mos ...
2022Design of an intake and a thruster for an atmosphere-breathing electric propulsion system
Francesco Romano, Thomas Binderup Jensen
Challenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that finally defines the mission's lifetime, unless a way to compensate for it is provided. This environment is named ...
2022The eta Aquilae System: Radial Velocities and Astrometry in Search of eta Aql B
The classical Cepheid eta Aql was not included in past Leavitt Law work because of a presumed complicating orbit due to a known B9.8V companion. To determine the orbit of eta Aql B, we analyze a significant number of radial velocity (RV) measurements from ...
2022Biomechanics at the workplace under hypogravity conditions
The main goal of my research is to establish guidelines for workplace design based on human biomechanics: specifically sitting workplaces and handling areas in 1/6G-1/3G (Moon, Mars) conditions. Such a workplace could be used in long-term space missions in ...
EPFL2022Preliminary Design of a Lunar Reconnaissance Drone
Erik Uythoven, Thomas Pfeiffer
In this report, a preliminary design study of a compact lunar reconnaissance drone module which will assist exploration rovers is presented. It is designed to assist future exploratory rover missions in difficult environments such as PSRs or extreme topogr ...
2022Discovery of a Binary-origin Classical Cepheid in a Binary System with a 59 day Orbital Period
We report the discovery of a surprising binary configuration of the double-mode Cepheid OGLE-LMC-CEP-1347 pulsating in the first (P-1= 0.690 days) and second-overtone (P-2= 0.556 days) modes. The orbital period (P-orb= 59 days) of the system is five times ...
Bristol2022Mechanical design of the optical unit and structural subsystem for a lunar camera
The project was initiated by the Moon Village Association (MVA). It is a non-governmental association which regulates the exploration program of lunar missions. The MVA also works on the development of space technologies: the Payload1 project is a part of ...
