Dealing with the conflicts of interest of credit rating agencies: a balanced cure for the disease
(Oxford University Press, 17 June 2022)Key points: The credit rating industry has long been plagued by acute conflicts of interest, which has led to a paramount level of rating inflation and the catastrophic failure of credit rating agencies (CRAs) in their ... -
Finite time output parameter estimation for a class of nonlinear systems
(Institute of Electrical and Electronics Engineers (IEEE), 17 June 2022)In this letter, a novel scheme is proposed to identify in finite time the value of an unknown output parameter for a class of nonlinear dynamical systems. Inspired by the Super-Twisting Sliding Mode Algorithm (STA), the ... -
A detailed analysis of the Gl 486 planetary system
(EDP Sciences, 20 September 2022)Context. The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3 R⊕ and 3.0 M⊕ that is ideal for both transmission and emission ... -
EXPRES. III. Revealing the stellar activity radial velocity signature of ϵ Eridani with photometry and interferometry
(IOP Publishing / American Astronomical Society, 16 December 2021)The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) shifts due to the presence of exoplanets. ... -
VLTI-MATISSE L- and N-band aperture-synthesis imaging of the unclassified B[e] star FS Canis Majoris★
(EDP Sciences, 3 February 2022)Context. FS Canis Majoris (FS CMa, HD 45677) is an unclassified B[e] star surrounded by an inclined dust disk. The evolutionary stage of FS CMa is still debated. Perpendicular to the circumstellar disk, a bipolar outflow ...
