The size evolution of star-forming and quenched galaxies in the IllustrisTNG simulation by Genel, Shy, Nelson, Dylan, Pillepich, Annalisa, Springel, Volker, Pakmor, Rüdiger, Weinberger, Rainer, Hernquist, Lars, Naiman, Jill, Vogelsberger, Mark, Marinacci, Federico, Torrey, Paul

“…This is partly because the main-sequence high-redshift progenitors of quenched z = 0 galaxies are drawn from the lower end of the size distribution of the overall population of main-sequence high-redshift galaxies. …”

The Sun in Time: Activity and Environment by Güdel Manuel

“…The Sun's magnetic activity has steadily declined during its main-sequence life. While the solar photospheric luminosity was about 30% lower 4.6 Gyr ago when the Sun arrived on the main sequence compared to present-day levels, its faster rotation generated enhanced magnetic activity; magnetic heating processes in the chromosphere, the transition region, and the corona induced ultraviolet, extreme-ultraviolet, and X-ray emission about 10, 100, and 1000 times, respectively, the present-day levels, as inferred from young solar-analog stars. …”

A search for debris disks in the Herschel-ATLAS by Thompson, M, Smith, D, Stevens, J, Jarvis, M, Perez, E, Marshall, J, Dunne, L, Eales, S, White, G, Leeuw, L, Sibthorpe, B, Baes, M, Gonzalez-Solares, E, Scott, D, Vieiria, J, Amblard, A, Auld, R, Bonfield, D, Burgarella, D, Buttiglione, S, Cava, A, Clements, D, Cooray, A, Dariush, A, de Zotti, G

“…We use a photometric selection technique to identify main sequence stars in the SDSS DR7 catalogue and a Bayesian Likelihood Ratio method to identify H-ATLAS catalogue sources associated with these main sequence stars. …”

EVIDENCE FOR THE TIDAL DESTRUCTION OF HOT JUPITERS BY SUBGIANT STARS by Winn, Joshua Nathan, Schlaufman, Kevin C

“…Indeed, it is well established that hot Jupiters are found less frequently around subgiant stars than around main-sequence stars. However, the interpretation of this finding has been ambiguous, because the subgiants are also thought to be more massive than the F- and G-type stars that dominate the main-sequence sample. …”

GOODS-Herschel: ultra-deep XMM-Newton observations reveal AGN/star-formation connection by Rovilos, E, Comastri, A, Gilli, R, Georgantopoulos, I, Ranalli, P, Vignali, C, Lusso, E, Cappelluti, N, Zamorani, G, Elbaz, D, Dickinson, M, Hwang, H, Charmandaris, V, Ivison, R, Merloni, A, Daddi, E, Carrera, F, Brandt, W, Mullaney, JR, Scott, D, Alexander, D, Del Moro, A, Morrison, G, Murphy, E, Altieri, B

“…Comparing the sSFR of the hosts to the characteristic sSFR of star-forming galaxies at the same redshift (the so-called "main sequence") we find that the AGNs reside mostly in main-sequence and starburst hosts, reflecting the AGN-sSFR connection; however the infrared selection might bias this result. …”

Analytic Models of Brown Dwarfs and the Substellar Mass Limit by Sayantan Auddy, Shantanu Basu, S. R. Valluri

“…We present the analytic theory of brown dwarf evolution and the lower mass limit of the hydrogen burning main-sequence stars and introduce some modifications to the existing models. …”

Simulating Self-lensing and Eclipsing Signals due to Detached Compact Objects in the TESS Light Curves by Sedighe Sajadian, Niayesh Afshordi

“…In a detached and edge-on binary system including a main-sequence star and a compact object (denoted by WD main-sequence (WDMS), NS main-sequence (NSMS), and SBH main-sequence (BHMS) systems), the stellar brightness can change periodically due to self-lensing or eclipsing features. …”

HerMES: dust attenuation and star formation activity in ultraviolet-selected samples from z similar to 4 to similar to 1.5 by Heinis, S, Buat, V, Bethermin, M, Bock, J, Burgarella, D, Conley, A, Cooray, A, Farrah, D, Ilbert, O, Magdis, G, Marsden, G, Oliver, S, Rigopoulou, D, Roehlly, Y, Schulz, B, Symeonidis, M, Viero, M, Xu, C, Zemcov, M

“…We use these results to discuss the star formation histories of galaxies in the framework of the main sequence of star-forming galaxies. Our results suggest that galaxies at high redshift (2.5 &lt; z &lt; 4) stay around 1 Gyr on the main sequence. …”

GOODS-Herschel: the far-infrared view of star formation in active galactic nucleus host galaxies since z similar to 3 by Mullaney, JR, Pannella, M, Daddi, E, Alexander, D, Elbaz, D, Hickox, R, Bournaud, F, Altieri, B, Aussel, H, Coia, D, Dannerbauer, H, Dasyra, K, Dickinson, M, Hwang, H, Kartaltepe, J, Leiton, R, Magdis, G, Magnelli, B, Popesso, P, Valtchanov, I, Bauer, F, Brandt, W, Del Moro, A, Hanish, D, Ivison, R

“…We estimate that 79 ± 10percent of moderate-luminosity AGNs are hosted in main-sequence galaxies, 15 ± 7percent in quiescent galaxies and &lt;10percent in strongly starbursting galaxies. …”

Planetary Engulfment Prognosis within the ρ CrB System by Stephen R. Kane

“…We present an analysis of a slightly eccentric (e = 0.05), partially eclipsing, long-period (P = 69.73 days) main-sequence binary system (WOCS 12009, Sanders 1247) in the benchmark old open cluster M67. …”

Early evolution of fully convective stars in scalar–tensor gravity by Débora Aguiar Gomes, Aneta Wojnar

“…With this in mind, we consider three evolutionary phases—contraction to the main sequence, lithium burning and entrance to the main sequence—and investigate how each of these phases is affected by the theory’s parameter. …”

Low-mass red giants as binary stars without angular momentum by Faulkner, J

“…I present new theorems and results involving these quantities, and then sketch a viewpoint which (i) links the structural and evolutionary behaviour of stars from the main-sequence through horizontal branch phases of evolution, and (ii) also has implications for post-main-sequence developments in more massive stars.…”
